OnePlus 9 and 9 Pro Android 13 completed, now what?

That is the same question that I had. I made the mistake many OnePlus 9 (Pro) TMobile owners did in downloading Android 12 when it first came out. It absolutely destroyed my phone. I tried to explain to the TMobile rep at the store that it was a "Software Issue" NOT a Hardware Issue.  The only remedy he offered was to send me a replacement phone. I received the new phone with the stock Android 11 Op System. I haven't updated since and my phone has been at risk because of the broken update.  I kept an eye on T-Mobile's update page and saw that it was finally "Completed."  Unfortunately it turned out to be the broken Android 12 instead.  So aggravated!
