Reminders not syncing properly

I have the same problem with my iPhone XS, iPad Pro and MacBook. Reminders is not syncing correctly across the 3 devices. Other apps like Calendar and Notes work fine.

Please let me know if you resolve it.

Hello errtrk,

Thank you for reaching out to Apple Support Communities, and we'll be happy to help in any way we can. We understand you're having issues with syncing Reminders. Try the steps listed here to see if they resolve the issue: If your iCloud Contacts, Calendars, or Reminders won’t sync - Apple Support

"Things to check first

1. Check the system status of iCloud Contacts, Calendars, or Reminders to check for services outages or connection issues.
2. If a reminder isn't showing up on some of your devices, make sure that your iPhone and iPad have the latest version of iOS or iPadOS, or that your Mac has the latest version of macOS.
3. Make sure that you're signed in to iCloud with the same Apple ID on all of your devices. Then, check that you turned on Contacts, Calendars, and Reminders in your iCloud settings.
4. Check the date and time settings on your device to make sure they're correct for your current location."

We hope this helps.

Cheers!

I have the exact same problem with my new iPhone 14 pro not syncing to iCloud and reminders not showing up on my iPad or Mac but not vice versa. I have spent 2 long 1hr sessions with Apple support but they have not solved the problem yet. They have submitted many screen shots,etc to the Engineers but I haven't heard back yet. If you solve this problem, please post and I'll do the same.

I’m having the exact same problem. Reminders work perfectly on my Macs, iPad, even my Watch. I have a shared Reminders list with my spouse that works flawlessly.

Except on my iPhone. Anything I create, check off, or delete on the iPhone is only reflected on the iPhone. Anything done in iCloud or any other device that’s properly synced appears on the iPhone. It’s just the iPhone refuses to send its updated info to iCloud.

What really gets me is my Watch even syncs correctly…

I’ve tried turning off Reminders in iCloud settings on my iPhone, turning off iCloud completely on my iPhone, and all the other troubleshooting steps referenced in the Apple support doc, with no change in symptoms.

I almost skipped this response, as I presumed I was updated since I always have Automatic Updates turned on.

Well guess what? My iPhone hadn’t updated to 16.2 yet. Did a manual update, and now my Reminders are syncing properly.

Thanks for the troubleshooting check!

Make sure you have all devices with up to date software. When I updated to iOS 16.2 on my iPhone, it solved all my syncing problems.
