That is odd. I'm using a Pixel 9, but I can't think of any substantial differences that would change how GrayJay would function. If you can grab a copy of your logs and send them to the dev team, I'm sure they could narrow down the issue better.
One thing you do have to keep in mind is that the Youtube source updates quite often (since ofc Google isn't a fan of it), so if something's really off, try updating that first.
I'm currently watching a YT video on my own install rn, so current implementation is functional.
