Tried the temporary fixes stated here but they don't work. On latest AppleTV version and Plex Pass media server. Unfortunately I get buffering problems during films. My NAS technically can't transcode yet it was working perfectly until last week. Any advise or fixed versions would be very welcome
Did you make any changes last week that you remember? Just thinking that we could narrow something down if we can figure out what change was made just prior to your issues. Your onset of issues is the most recent I have heard of in awhile.
