I also flew united recently and, in addition to the free messaging access, they also provided free access to the inflight entertainment, in case you wanted to watch it on your device instead of on the screen.

I would have loved to take advantage of this since my wireless earbuds were significantly better than the wired pair I had. Unfortunately, a little pop-up warned me that this was not available on Android 13 devices. I was more than a little annoyed, but also curious as to why this might have been the case.
