Why do push alerts go to my old iPhone
I just upgraded to the new iPhone 13 yesterday. Everything transferred to my new phone from my old iPhone just fine. Today, when I tried to access my work email, I waited for the push alert to come to my phone. I heard a buzz on my old iPhone, and it turned out that the push alert went there instead of to the new phone. What caused this? Or more importantly, how can I get the push alert to go to the new iPhone?
