Because Plex is only allowed to use IMDb data for movies, but not for TV shows.
This has also been the case with the old agents. There is nothing new about it.
It’s a shame they can’t get permission to use tv ratings…
Sorry another question why is it season posters are not pulling through from TMDB I am having to copy url from TMDB for shows where I prefer their posters
I just edited my post as I realized I misread what you wrote, so sorry about that.
However, I have not upgraded my TV library yet (I will more than likely do this manually just because) but I have had my movie library upgraded for probably a year now I’m guessing (I think I did the upgrade shortly after that came out of beta, but again I feel that upgrade was handled differently then this and/or I did it in a manual way as well).

I am trying to understand this part. Under Agent when I go to match a show that didn’t get automatically matched, it says “Plex TV Series”. There is a dropdown option under Agent, but only “Plex TV Series” is available. It would be great if there was a TVDB option here!
So how can I over-ride “Plex TV Series” for one show? Also, by show, do you mean series? Or just one single show.
My work-a-round is pretty complicated and I wish there was a drop-down option for TVDB, under Plex TV Series when you are at the Fix Match screen.
My work-a-round is to go to the advanced library options, change agent to The TVDB. That gives me a notification that I need to upgrade library. So I upgrade library AND UNCHECK “Refresh metadata for this library after upgrading”. This works for me but is a pain.
I use Plex in combination with “Channels DVR” so i’m not archiving these particular episodes. I am constantly adding (through Channels DVR) and removing shows, daily. So when an episode is removed, the next time a new episode is recorded, it must be matched once again.
I was just thinking that you probably should first upgrade before you give advice to the other members. All your advice is speculation based on @OttoKerner posts. Just a thought and not an attack. I appreciate the effort.
Otto wasn’t referring to actually changing the agent.
You can specify the preferred episode order on the library level (⋮ > Manage Library > Edit... → Advanced > Episode ordering
You can override that preferred episode order for each show (on the show: 
> Advanced > Episode order
Thanks. I realized that after I posted. There should be an over-ride option so my point still stands. The work-a-round I use should be streamlined some how.
Except my post was based on my experience with the movie agent upgrade (which from the guid standpoint is going to be similar as Otto confirmed that the guid will be changing) and I wasn’t really giving advice, just explaining the reason for why the metadata refresh is needed to make the upgrade complete.
The only incorrect thing I really said was based on the post of yours I quoted as I mis-comprehended what you wrote. Pretty much everything I said, with maybe the exception of what I originally wrote in response to my initial misunderstanding of your post, is just explaining stuff and not giving any advice.

How do you know if you are right it you haven’t tested it yourself b upgrading your libraries?
If I was wrong, I invited any Plex employee to correct me.
Also, knowing this member base, if I was wrong I am sure another member would have corrected me with the information.
Plus, as I read pretty much every post in this thread, I had read this post by Volts which confirms what I said.
So yes, there is a chance I could have been wrong, but I was going based on the last agent update that Plex did and the knowledge that Plex works based on the usage of the guids for a lot of things in the background.

You don’t change the matching.
If you’d rather like to use a different episode ordering, edit the show.
I am using Plex terminology.
a TV Show (e.g. “House, M.D.”) consists of one or several
Seasons, which themselves can have several
episodes in them.
I give up. I will take what you give us, even though it used to work before, and now it doesn’t , and like it 
There should be an option to bypass the new Agent through the dropdown box for each series (under Plex TV Series). Nobody asked for the agent options to be removed.

This is what I have been screaming into the void about - the removal of additional agents/agent prioritization is a HUGE regression.
Do you know if something changed and they were forced to do this? If they don’t tweak this then it is a major regression. I am done screwing with this in this (crappy) form.

All I know for a fact is that they wrote the new agent in C++, while the old agents were written in Python.
Why they chose to write the new agents in C++, I don’t know.
Why they chose to freeze out the development community by developing in C++ and not providing a framework like they did with the python agents, I don’t know.
Why you can’t just alternate between agents is beyond me.
Overall, I am very disappointed with the change and I’m sticking with the Legacy agents until they pry them from my cold, dead hands.
Things like SubZero and Lambda are completely dead in the water, as are other 3rd party tools.

I added all the shows that didn’t match with the upgraded agent (worked with TVDB but needed to switch agent in the advanced library settings to TVDB), and I am pleased to say, that once I added them to the TMDB, they do indeed match automatically with the new Plex TV Series agent.
This sounds like a nightmare so I don’t want to do it. My movie collection is large, so going through all of it to manually change all the artwork again is not something I want to do. I tend to pick the actual movie poster (which plex rarely does by default) and not the other alternative or more basic artwork.
My question is: Is there any way to tell Plex I don’t want to upgrade? Or is it always going to display that orange arrow telling me I should upgrade my libraries?
The workaround is to go ahead and upgrade library but uncheck the box “Refresh metadata for this library after upgrading”.
I urge you to NOT do that. Because as explained above: Should I "upgrade" my libraries? - #203 by OttoKerner
Thanks. That makes sense.
I upgraded all my libraries. The issues I had were solved by adding missing titles to the TMDB database, waiting a couple days, and rescanning library files.
