Calendar doesn't sync since iOS 17.3.1

Like most, utilize a number of calendars. Since iOS 17.3.1 uploaded on my iPhone 11 Pro, the calendar won't sync from my desktop (ATT/Yahoo email). I've done all the customary steps: change passwords, delete then reinstall. Anyone have a "fix"?

I recently helped a friend with this issue. Below is the "fix":


Navigate to Settings > Mail > Accounts > Tap on the account in question (Yahoo, Gmail, etc.) > switch on Calendar


This should instantly re-synch calendar events to your Apple Calendar app and you should be able to search for past and future events again. It is worth noting that when you create an Event via Apple Calendar, pay attention to which account you are actually saving it to. For example, if your default account is Yahoo, you're actually saving it to Yahoo calendar while Apple Calendar is just a proxy.


Hope this helps!

After the last update to Ios 17.3.1, my yahoo calendar isn't synchronising anymore. I did everything during more than 3 hours to reconnect (deleting the account, new install, ....) but nothing is working. I've seen in the meantime that I'm not the only one with this issue, so must be a bug or something.


Please help because I'm very depending on my yahoo-calendar on my phone


Thanks in advance

Actually had an online, screen sharing session with an upper level Apple tech for almost 1-1/2 hours. Tried so many fixes, computer anxx do account alterations, etc. In total, I had spent almost 6-1/2 hours trying to resolve the issue. In the end, nothing worked.


Then, this morning, my calendar was synced 🤪. No rational explanation. At this point, just hope it’s sustained. My best guess is that Apple IT did a patch overnight.
