iCloud Reminders issue?

[Ploki]

My reminders went out of sync for some reason and after turning it on/off a couple of times on both mac and iPhone, they right-out disappeared.
On iCloud.com only one list remains, and when i re-enable them, not even those sync - so it shows 0 reminders.

and now reminders even crash on icloud.

My Reminders sync is completely screwed.

I can see them on iCloud.com but they won't sync to my devices: iPhone 12, iPad Pro 3rd-gen, 2019 iMac 5k. All with latest software.

Tried everything—switching off Reminders sync in iCloud, signing out of iCloud, etc., etc.—all while rebooting in-between.

I believe that one recurring Reminder is corrupted somehow—but since one can't mark a recurring Reminder complete on iCloud.com (let alone delete it), there is nothing to be done. Once in a while, a device will sync from iCloud—but never back to iCloud, so I am similarly unable even to delete my Reminders or Lists, to start fresh.

This is just appalling—I guess I need to hit up Support...

Same thing happened here. It was a recurring reminder that seems to have triggered it. I disconnected all devices except one from iCloud, deleted everything, also on iCloud.com, and it seems fine now.
