I have a Sharp Roku tv. Everytime I launch a streaming app, be it Netflix, Hulu, prime, YouTube, it crashes less than 30 seconds in and reverts to the Home Screen. Streaming freezes constantly if you can get it to even load. I have tried uninstalling and reinstalling the apps, I have tried the Home Screen 5x ffwd and rwd trick and done a factory reset. Nothing works. My internet connection is excellent with fast up and downloads so it’s not an internet connectivity problem. My gf has the same issues with her Roku tv. Judging from Google threads this is a frequent and known issue with Roku with no known fix beside what’s been mentioned and isn’t working.
