Pixelation/Rendering Problems on Apple TV+ app

This problem has previously been posted with no real answers. Only advice to turn off/on the tv, reinstall the app or ask people in the house not to use the internet.

Can someone please help?

I have a TCL Roku 55 Android 2020 tv.

Have other streaming services, Netflix, Amazon Prime, Roku etc. and all are ok.

TV works fine, there are fresh batteries in the remote.

I've been with Apple TV+ service for over a year and had no issues until today.

Today I've started the Apple TV+ app and wanted to continue watching the series I've started yesterday. The video was scrambled/pixelated, like it was frozen, there was no sound, but I saw the subtitles changing, meaning that the video was playing in the background.

Tried to watch 10-12 of Apple shows, and I got the same scrambled/buffering problem.

I've tried the following but nothing worked -

• Restarting the Apple TV+ app
• Resetting the Apple TV+ app
• Removing and reinstalling the Apple TV+ app
• Turning my tv off and on
• Restarting my internet/network (1 Gig network)
• Tried the Apple TV+ app on multiple browsers, on my PC - the video could not play at all, I got a blank screen when clicking "play" on at least 10 different shows.
• Contacted Apple TV+ Chat support, who redirected me to a higher level support, where I've done the same things again with the senior support person.

I would love to keep the Apple app, but this is a real turn off.

If this is not resolved in next 2-3 days, I'll cancel my subscription, as this is really frustrating.

Any help is appreciated!
