[Q] Fire TV Playback Issues topic

I'll start by saying I've had my Fire TV since April and never had a single problem until about a week ago I started having problems when using Plex and Netflix. Anything I tried to play on any settings would play for about 20 seconds and then stop. I ruled out any problem with my network so it had to be the Fire TV itself which updated to the latest version a few days prior to the problems starting. I talked to Amazon support for a few hours and after all the troubleshooting they had me do they sent me a new Fire TV which got here today but it automatically updated during setup and I'm having the same exact problems I was having with the other one. Amazon instant videos won't load at all, Netflix/Plex play for 20 seconds perfectly fine then just stop, and Sling TV plays for about a second then buffers.

I'm here hoping somebody knows how or can figure out a way to downgrade because this is beyond frustrating.

My Fire TV is on Software Version 51.1.4.3_user_514020320
