iCloud calendars not synching anymore

@Katie - I spent an hour on the phone today with Apple Support and ended up being escalated three different times. In short, Apple acknowledges the issue and also indicated they recognized the "uptick in support forum activity" regarding calendar sharing/syncing.

I ended up sending a bunch of screenshots/videos directly to the Senior advisor I ended up working with. I suspect this seems to be something not necessarily account specific, but would suggest you contact Apple Support directly to ensure your specific account/issue is logged.

I called Apple almost a week ago. One day after the problem started. I’m also in contact with a Senior Adviser and had to send some screenshots to make it clear it happens on multiple devices, multiple MacOS versions and even on iCloud.com.

I would suggest everyone to call Apple directly as they don’t read/respond on this forum. We have to make clear this is a serious issue we’re having. Please don’t think “some people already called so I can just wait now”.

They need more tickets/bug reports in order to give this priority.

Same issue here (started last week) with a MacBook Pro m1 max on latest Monterey 12.1. Called apple support, ran a couple of tests, including clearing caches, creating new user, unchecked calendar in Apple ID, re-login of iCloud etc.. They told me they are escalating this issue to higher authority and will contact me again.

Interesting! I have the exact same issue. And we’re not the only one: https://communities.apple.com/de/thread/253475706

I found a similar post on the German discussion forum.

Mine is doing this too. It also appears to be mismatching calendars... .

My wife is also experiencing this problem on her account with a calendar she shares with me.

same issue here... caused problem during holiday time!!!

@apple please any comments?!?

Same issue. Escalated it onto Apple Support and then engineering. It seems like it's working today...

Yes ! It's working again on my end !

I will also join the chorus and happily state that my calendar issues seem to be fixed this morning!

Works for me , too since today.

Hi,

Any ideas?

Thanks

Having the same issue. Tried multiple solutions and none worked.

My calendar is different on iPhone, iPad, MacBook calendar app, and iCloud.com calendar.

This same issue has been occurring for me the past few days.
