That's fair. It was rude and I'm sorry about that. It's not my style at all usually. I've been trying to get an answer from several sources, nothing actually answering the question directly. Just kind of roundabout answers. Or, on Reddit, they don't even publish. Not an excuse. Again, I'm sorry. And thank you for trying to help.
I do understand the risks. What I'm wondering is this:
Are you saying that this is legitimately a "you definitely need to restore the iPad for updates to work again" case?
Or is it a kind of a thing where there is a conflict between the newer beta version installed on the iPad and the older public OS on Apple's server, and will sort itself out when the 16.1.x is available since there will be no conflict then?
It sounds like OP ran into the same thing I did. If it sorts itself out once the public OS catches up to the beta each of us has installed, then there's no need for a restore.
Does that make sense? It's difficult to explain.
