Youtube app stops video buffering ?

My ipad : ipad pro M4 11 inch with ipados 17.6.1 (it had the same issue with 17.6)

Anyone knows how to solve this ?
The app works but most of the time either the content (movie, not the app itself) won't even start and just has the spinning icon or if it starts it'll buffer a bit of video and then just stops while playing.
It doesn't load in the next chunk of data.

I tried removing/reinstalling and even reinstalling the ipados itself but no luck.
It is not a internet issue since i can remove the app then use safari/chrome and get perfect 4k 60 hdr playback !

While i can get used to the safari approach i rather like the youtube app itself and want to see if anyone had the same issue or was able to resolve it ?

I am not using ANY kind of adblocking software at all, just stock ipadOS.

Thanks !
