Plex collection background wont work

Hello ,

I have 3 problems which i can’t seem to find a solution for.
1: if i load a background into the collection tab, it wont show. I see a refresh when i have the collection open on my TV , but i dont see a change. Its just a 2 color blurred image with no details.

  1. On my other TV , a LG with webOS , my server can’t be found. Could the problem be that its not directly connected to the router but to the wifi booster? I will try now to connect the TV through wifi and see if that helps.

3
When i set ‘show collections’ to disabled they are inline , i dont want collections to show in my library. Not inline , and not as a collection in the library. Only when i go to collections.
When i set to disabled they are all inline.

Problem 1 solved.
Collections showing while disabled still showing

  1. Disable secure connection in the Plex app on your TV.

  2. Edit your library > Advanced > Change the last option to Disabled. The collections will be hidden from the Library and only shown on Collection.

Thats what i did but the movies are still in my library.
Also , i am trying to make the play trailer button working by putting the trailer in the movie directory , name it theatrical trailer 1-trailer.mp4 , set 'play trailers for library but still the play trailer button is not there.

I got all things working , but now i have another issue (yes, another) ,
I messed up my agent settings because of trying trailer addict plugin , and now many Movies have wrong metadata, posters… And can’t get it fixed
And i i cant change the scanner. Always says cant save. Even when selecting plex movie for both scanner and agent.
Any help?
