I upgraded to the 15 pro and then returned the phone and went back to my 14. At no point in time did I ever erase or restore my 14 so all info was intact. Today I can’t find any of my past appointments and super important events in my phone. And when I search for things- it comes up as ‘no results’. There are two other things going on. Occasionally I can look at the event (if I remember the date that it happened and find the event but can’t search it. That’s not always the case). And- when I click on calendars, all of my accounts have a red exclamation point next to them but don’t seem to have login issues and there is no alert statement for me to work out what’s going on. Help… I’m losing my mind as I need these appts as I schedule my life by them! Thank you!!
