Apple shared calendar not syncing all events between devices

My family and I have a shared iCloud calendar. It’s saved many a family arguments of what’s happening. That said I put in last week an event. It showed up on my iPhone but not my iPad. Same with an event my dad added about seeing a play. It was in it earlier today but now can’t be found. Any thoughts/assistance?

I had this happen awhile back and it was the Two-Factor Authentication for iCloud wasn’t quite working properly on my kids iPhones. I just had to go into their iCloud account and enter the password and the TFA and it was working again.


Hmm ok. How would I do this on my own phone? Sign out of iCloud and sign back in?
