I have had this bug for a good long while now.
Whenever I pause playback on the web client (Firefox, Edge and Chrome on Mac and Windows) it is able to resume the playback when un-paused from the moment it was paused. But if I leave it paused for more than a minute or so, it is able to resume playback until the buffer runs out and then it just freezes and you have to reload the page to restart the playback.
I saw someone on the forums mention the same problem and they suggested changing the “Terminate Sessions Paused for Longer Than” setting… I’ve got it set to 45 minutes and it’s still happening.
