I am having some issues with strange behavior with Plex, Alexa and multiple clients. This behavior seems to have changed over the months since setting up Alexa. I have multiple Plex clients of varying type and multiple Echo devices.
I have my Living Room TV (Shield TV) set up as my primary player for Plex/Alexa. Everything works pretty well except for some of the issues discussed here in this thread.
When I try to use Alexa to start playback in any other room (ex "Alexa tell Plex to Play XYZ on Loft TV") it works I can then even try another location. But whenever I want to watch on Living Room TV again, it will not work without assigning it as my Primary Plex player again. With Primary player I don't need to say the room name/Plex name afterwards, but I realize that after using Alexa to play on different Plex player I should (and used to have to), so I say "Alexa, tell Plex to play XYZ on Living Room TV" , it will not let me return to using my primary player, again, without resetting the player as primary. I can switch around with my other clients...
Any help would be appreciated.
