Quality only bad at netflix, why?

I just wanted to watch some movies on Netflix. Only I have the problem that the videos only in 240-360p run. So it looks like at any rate. I have a very good internet connection and YouTube videos are funny enough even in 4k.

Only with Netflix the quality is very bad and for example Tiktok load the videos very slowly

Does anyone know why this could be or how can I manually raise the quality at Netflix?

Possibly. Call the customer service. Have to look in the settings. There's the phone number from the customer service.

It may be that the number is displayed only on the PC, but not on the TV. Have to check.

They can certainly help.
