For example, in English it’s a common mistake to write “it’s” instead of “its”. Example: “The car is missing its mirror”. I’ve seen countless of times people writing, incorrectly, “the car is missing it’s mirror”.
It’s still a mistake even if native speaker do it, and it’s pretty common.
Ah yes, of course. If you had an actual Android TV you could install SmartTube which hides ads just like ReVanced. But I don’t think it works on a bare Chromecast
