Hi. Did factory reset fix the issue? I read comments from people from different country with the same issue, that means this issue is worldwide and Apple needs to fix it asap. I'm dealing with this issue for 2 month since 16.4. I opened a case with Apple support back then. I'm still waiting for a fix or an answer from them. If you call Apple Support please open a case. The more people opening a case the more lucky we are from Apple to look at the issue and fix it. That is what a Senior Adviser from Apple to told me...
