Plex slow using app but works fine using webplayer



I can't get my Plex app to Chromecast any of my video files. They all buffer every 2 seconds making it pretty much un-watchable. If I use the web player on the exact same devices the same videos play fine. This happens on my android phone and my wife's iPhone. What could be causing this?


I have tried playing around with the quality settings in the app but nothing seems to help.


Same issue here. Any updates? Thanks
