LG oled apple tv+ stuck

Hello,

I have a brand new lg oled 77 inch smart tv.

Trying to use the apple tv+ app on the tv, it starts, sometimes, but stuck after few minutes, or even seconds sometimes

My internet speed on the tv is 100Mbits, fully allocated to the tv.

Other streaming services like netflix, disney are working perfect.

I tried reseting the app to defaults, uninstall the app and hard rebooting of the tv, nothing really helped

Any help is appreciated.
