I know this has been reported already a thousand times but it’s absolutely ridiculous.
Since Plex Server 1.9+ subtitles started appearing and disappearing at random during the view, but for most of the time they are not displayed.
Even more ridiculous is that on plex website it’s impossible to find older versions. I luckily had in my AppData folder the older installers and guess what, uninstalled and reinstalled the latest 1.8+ version I had and it works like a charm.
Seriously, it’s been months since this problem appeared and noone is taking care of it. At least give us the option to download an older installer so we can revert in case of huge problems like this.
