Apple tv will not load movies from streaming apps

My Apple tv is slow On streaming

Hi i got the newest generation of the Apple tv 4K without Ethernet so only wifi.

I got some issues with it that i just cant figure out so im calling for help.

So the issue is that streaming services such as Disney+, Netflix, F1tv in general all streaming apps cant load in movies/videos.

It seems like an bad wifi connection but YouTube videos Even in 4K loads and plays immediatly. And when i download apps from the app store the apps also downloads asap. 

i have done a Speedtest that shows i got 544Mbps in download and 454Mbps in upload, 3ms in ping and 1ms in jitter by Ookla’s Speedtest app and it shows that the wifi speed is there

I have tried to reset the Apple tv back to factory settings and checked apps and the Apple tv for updates today 22 september

On my Samsung smart tv everything works fine?

I just dont know What is wrong and i hope somebody here knows the solution to my extremely wierd problem.
