I would likely pay for youtube premium if the TV app wasn't so absymal.
However, having something that does not allow sorting by 'new' (and constantly recommending videos that are many years old), regularly re-introducing channels that have been marked as 'do not show' along with injecting the popular junk into 'for you' despite me having constantly marked similar as 'not interested'.
There is no way I will pay premium for such a terrible experience, even if it does remove ads. The TV experience - where I consume most content - is fast becoming the biggest reason to never use youtube.
