Shared Calendar not syncing across devices - weird bugs and error messages

[liamski]

My wife and I currently have a shared google calendar that we access via apple cal, but we're dumping google.

I set up a shared calendar on my imac, invited her and she joined. The calendar appears on my macbook, phone etc.

We needed to migrate our existing shared google calendar entries - including recurring and all day events - so I exported a calendar file from Google Calendar and imported into iCloud. Seemed logical and the online guides recommend this.

What's happened since is..

-- my imac had all the events, but my macbook only had some, as did my iphone. There was no pattern to this, eg: it wasnt just recurring events missing

-- she can't see all the events I imported

-- I got a 503 error message in macOS calendar and a failure to refresh message

-- I logged into icloud.com and not only was I greeted with login issues and an error about maintenance, but the calendar onscreen had literally nothing I'd imported in it

Has anyone else had similar issues and can recommend a solution please? It's a weird combination of google cal perhaps not exporting every event, but then icloud failing to sync across devices in the way you'd expect it to

Maybe give it some time? It may be that copying all those events over set off some event adding limit that flagged your account.

Thats a really good shout. The historical events go back to about 2012 so I forgot that could be quite a big ingest. Thanks

Since some of the calendars are showing across your devices, I’m guessing this ins’t it, but did you import them as iCloud calendars? It’s been a while, so some of my terminology might be off, but you can import calendars as either iCloud ones or as on device ones. The on Device ones will obviously not show up on all devices. I’m not sure if they will share correctly with other users or not. Whereas the iCloud ones obviously will

Thanks for checking that. I did indeed import into an iCloud calendar. Cheers

this is spot on. Apple’s syncing in particular can be wanting when there’s a large amount of data to sync… tends to take longer than you may expect, and more significantly there’s no way to check status (other than with Photos, which has its own issue in that you can’t force a sync)

I know this is an old thread but if you happen to see this I am having the exact same issue. Imported a large amount of calendar entries and iCloud is throwing out 503 errors. Were you able to ever get the calendar to sync? If so did you just leave it to sync or did you have to take any manual action?
