Apple account verification popup
This is keep poping up every day, it's very annoying, I tried literally everything to prevent it, nothing helps. I don't want any solutions and suggestions anymore, I just have one question: is it safe to bring back my iPhone to factory settings in this conditions? That is the only thing I didn't try, but I'm scared to do it because this Apple account verification popup is not from my current Apple ID that I'm using, it is from my old Apple ID which is deleted months ago. So can anyone confirm with certainty that I can bring my iPhone back on factory settings safely? Thanks in advance.
