Hello does anyone know if it is possible to block a particular channel from YouTube via the YouTube App?
Yes, it would be an Apple iPad, but the app is from YouTube (aka, Google). That's why I suggested contacting them.
... and yes, if someone here came across the same issue, I'm sure they will chime in to assist you with their solution. Good luck!
Have you tried YouTube support with this question?
YouTube is not an Apple product, best you ask the app developer on their website/forum for support.
FYI: Any feature or option in a 3rd party app must be implemented by them, let them know.
No I have not, I figured since it’s an Apple iPad, this would be the best place to ask. Surely someone else in this world has wondered the same thing.
