I have a Huawei p30 pro.
When watching YouTube via the app, I can only watch videos up to 480p, if I do it up to 1080p nothing happens and goes back to 480p. Sometimes the quality is even set to 240p.
When I watch YouTube on my laptop I can watch 1080p normally and on ps4 too.
Does anyone have any idea why this might be?
Possibly. Activated the option to reduce the quality of mobile data in the mobile settings?
How do I look that up?
Unfortunately I don't have Android, but with iOS you have the option in the app settings.
