Server Version#: 1.21.3.4014
Player Version#: 4.51.1
This has been raised before but on the basis of the Sharing Tab simply not being available. I am raising this again because we now know that the cause is (in my particular case) the Adblock Plus extension for Chrome.
When “app.plex.tv” is whitelisted in Adblock Plus the Sharing Tab appears when you edit a movie within Plex. When “app.plex.tv” is removed from the whitelist of Adblock Plus then the Sharing Tab does not appear.
The question I have is WHY?
I spent a long time searching for an answer and finally found some comments that made me look at the adblocker as a source of the problem. I think it took so much time to find an answer because the search criteria is generally along the lines of “plex sharing edit movie label” and this just provides lots of answers to a different question usually to do with managing server shares which is just different.
If anyone has an answer then I’d be very grateful indeed for some insight coz I’m baffled!

The problem lies within the ad blocker in your browser and not within Plex itself. Although Plex could be updated to remove the issue and there is a good argument for doing so, the problem can be solved without an update to Plex.
The ad blocker in your browser is incorrectly identifying part of the rendered web page within Plex as being an advert and it therefore removes it. Removing ads is what we want ad blockers to do after all. However in this case the ad blocker just gets it wrong and removes something we don’t want it to remove, namely the sharing Tab within the Edit Movie popup. See below for the technical details of why.
Quickest and easiest solution is to whitelist Plex (https://app.plex.tv) within the ad blocker extension.
As Plex does not serve us any ads within the media player then any ad blocker will provide little, if any, benefit when using Plex.
Just remember that you will have to whitelist the plex url in every instance of every browser you have that has an ad blocker extension installed which is the main argument for having Plex updated. If the Plex developers could make this simple change then many many hours of users time would be saved.
