Terrible streaming experience Apple TV App

I currently cannot watch a single programme without at least 20 interruptions. I have Netflix, prime, Disney Plus, Discovery Plus, they all stream fine when my tv is connected via WiFi, since using Apple TV app I have connected my TV via Ethernet and still it will need to buffer. I have even tried changing the quality to SD but this makes no difference. I can only assume this is a software issue. It’s taken Apple a long time to add the ability for older tv’s to have the application and it’s very disappointing that newer providers can build an app and release in a shorter time. Come on Apple this is not good enough.
