ios 15 sync issues

Hi - since you seem to potentially be a source for solutions

I updated IOS15 today - with the consequence that my five-six shared calendars became all jumbled up. Appointments have ended up in entirely different weeks and months even, and at different timings.

I have tried to uninstall a calendar an re-sync, to no avail. It is utterly frustrating and already after a few hours come at a great cost in terms of missed appointments.

I am desperate to get this back to normal. All calendars seem to be inputing appointments in the wrong dates and times now. There is no logic in terms of time zones and such. it is even graphically screwing up appointments being put on top of each other and becoming illegible

I have restarted the phone twice. Closed the calendar app several times (by swiping away in app-switch mode) and un -synced and synced again

please please help!

Hi diw45,

Thanks for reaching out using Apple Support Communities. Here to help.

It sounds like you're having trouble with Calendar syncing.

Can you explain what's happening a bit further? Are you not seeing any events on your iPhone? Are changes not syncing to your other devices?

The below article will assist with troubleshooting the calendar connectivity. You may want to check that your calendar accounts are still connected within Settings > Calendar > Accounts.

If your iCloud Contacts, Calendars, or Reminders won’t sync

Let us know if the steps in this article are helpful, or if we can assist further.

Take care for now!

This is becoming dangerous. I am

missing work meetings, birthdays - my kids’ extra curriculars.

still appointments appear in wrong spot, not only wrong days but also wrong duratiom, wrong time of the day. Everything is wrong.

I am really desperate and quite ****** off.

i have

• restarted
• reimstalled calendars
• deleted calendars
• re-created appointments
• synced and resynced - the calendar is still completely useless

please please please help!

Entries in Calendar on my Mac do not appear on my iPhone or iPad but entries from either my iPhone or iPad do appear on the Mac. I don't think this problem existed before I updated to IOS 15 (and the subsequent mini updates). All three devices are signed into the same iCloud account and all three devices have been updated to the latest software versions..

Hi. I have exactly the same issue on my iphone and ipad. It is impossible to use the calendar with entries not showing or appearing in the wrong day and time slot. Has only happened since upgrading IOS

Thanks Mark

I am having the same issues - my calendar is completely jumbled and constantly changing with no sense to it ever since I updated to ios15. So far I see no answers I the community, but like others it has rendered my phone calendar useless and hopelessly confusing. I called Apple but the tech seemed to have no record of this problem, nor was she able to help me. I hope someone has figured this out

I think i have now scanned every available conversation on this - and apple staff are nowhere to be seen - neither are any real solutions. This is truly infuriating. Calling apple is futile. They say restart reinstall re-something. To no effect. Does anyone know how to reach anyone who can actually help? I am considering sueing to be able to return a phone that has lost about 25% of what i would consider its main functionality for my use.

Anyone been able to solve this?

Had the exact same issue arise (and still unresolved!) after updating to IOS15.2

have meetings appearing on completely wrong dates / times, 1h meetings have even become full day events on different days. Sometimes if I click on a meeting title it then opens a different event.

No apparent pattern either.

I am having the same issue with my calendar since updating to 15. Appointments jumbled, stacked, missing, synced work systems not communicating, Standard trouble shooting has failed. Its on my work platform and is going to result in transitioning away from IOS if a fix doesn't appear quickly. Has anyone successfully navigated a fix?

Thx

I had the same issues with one specific shared calendar after iOS 15 update.

It was not syncing old events on a certain device, no matter what.

We ended up making a new calendar, and move events from the old to new. And seems to work so far.

it really bothers me I couldn’t get _that_ specific calendar to work but … whatever. Hope it helps someone

hi,

I am experiencing the same thing… how do I get my calendars back in line… I’ve lost all confidence in knowing what my schedule is.

please help :)

I am having same issues. Please help!

Omg im experiencing the same issue, everything doesn’t sync. I’ve logged out, signed back in, tried from different devices. Calendar is so messed up I have no idea whats going on.

Has there been any movement on this, the iCloud calendar is a complete mess
