I got that big warning about having 2 videos left before being locked out of youtube viewing due to running an "ad-blocker", that was last week, I've not watched a video on the site since.
I just download it with yt-dlp or throw it in to mpv. If those stop working I'll probably just stop watching youtube altogether since I only watch maybe 6-10 vids a week anyway. This "app" does look quite good, but for how long it will work if g**e keeps making it difficult I don't know.
