I know this has already been discussed, but the answers take me back to 2018. No matter what app I'm using, Hulu, Disney, YouTube TV, Sirius XM, etc. I only get about 2 minutes of screen time before it takes me back to the home screen. Heck I even tried watching Dirty Rotten Scoundrels on Crackle and I couldn't even get passed the credits. I've tried all the solutions presented in these discussions and nothing is working. I have a Vizio 50" plasma (I know, older) but it still works great. If ANYBODY had any suggestions that worked, PLEASE, let me know! Thanks in advance.
So you have an express.
Whst is your Settings/Display settings try 1080p.
and then Settings /System restart
might be time to upgrade.
