I've been using Plex with my Chromecasts (own 2 ver 1) since it was possible (first using plex pass) and later when it was available to all.
Everything worked well up until few months ago.
I have a problem where I cast a movie with subtitles (no matter which language) and everything is fine up until a certain moment they disappear. The movie keeps playing as normal but without any subtitles.
When checking on the plex app on my phone, the subtitles are sometime selected and sometime not.
This can happen several times in a movie.
If I disable the subtitles and enable them again using the settings icon, they reappear but will disappear again after several minutes.
It started around the time the new chromecast was out but I'm not sure it is related.
This happens with 2 different chromecasts and 2 different routers.
Anyone experienced this?
