I am not going to make much effort to tell you that in my opinion all apps that were made for android and raspberry/kodi/libre-elec suck as hell. (excuse my French!)
Subtitles run away, keep running away. switching them to other is stopping movie, go to settings, go to subs, tap the other sub, esc out and resume movie. The ‘L’ key in previous APP does nothing, finding via those settings another working subtitle does totally not work; 11 out of 10 times it fails. Control is buggy as hell, rebooting is almost the only way to get the thing working.
Subs on Chrome work flawlessly, yet any app that is on RaspberryPi or on all my android devices suck big time.
Now we can go discuss this at length, but if someone has anything to say in the presentation of those line of APPS, please do something about it. In the mean time all I want to know, is there an alternate device that I can use to watch my plex server content? and preferably not android, raspberry, because that platform is too difficult for the developers of the apps.
Oh, and in case this closes before anyone has the courage to respond, I counted on that totally to go without response… Prove me wrong!
