Appletv streaming app is very pixelated on my tcl roku smart tv, why?

Same issue and no other streaming app has an issue

An update just appeared an hour ago that fixed the pixelation. The picture freezes every so often, though, but it’s way better than the pixelation!

Same issue here. I have two TVs and only the TCL roku has the issue. Other non-tcl roku tv works great. My app says it’s current, no updates to perform so not sure what can solve this.
