So the issue I opened in April and then was fixed sometime before June 17 has returned. Full details are here in this post: Issue with DVR guide & two plex servers each with its own tuner.
The one good thing is the issue isn’t as much of a pain now. Now all I need to do is close down the plex player (whether it’s on my Fire TV stick or my web browser), reopen the plex player and then go to the new server / livetv guide I want to view and it shows the proper guide data. There just seems to be something with caching that data that if I try to switch between live tv & dvr on different servers the guide data is always for the first one to populate it until I close the app / player down and restart it.
