For the most part the issues you are experiencing now are prevalent among many if not most "Smart" TV's

Part of the issue is the apps themselves.

If you are developing cross platform apps you build iOS and Android first. If we were talking an Android phone for example we develop for Samsung and google Pixel devices because they represent 75% market share combined.

The remaining 25% of devices will be anywhere from 100% supported (because they are vanilla enough android) to doesn't run at all.

There's really not much point in developing or updating / maintaining apps for those "maybe they work, kinda, sorta" fringe devices.

I don't buy Smart TV's, I buy dumb TV's and hang an Apple TV off them. Your net investment in a dumb TV and dedicated streaming device is on par with the cost of a Smart TV and you get better performance, flexibility and reliability.
