Google Calendar items disappearing on Mac OS X 10.13.3 and IOS 11.2.6 Calendars

yes we tried to do the "sync only one year or x months" like the old outlook calendars would allow us. My work account is full of crazy items that Apple "skimmed" from my emails (ohhh never thought of that...maybe that's what is crashing it as calendar is sucking down events from my tens of thousands of emails).. I know that apple has a limit in size of calendars https://support.apple.com/en-us/HT202158 Max size of all calendars (excluding attachments) is 24MB... that's why it's crashing when calendar cache (DB) gets to 32.5MB. Apple is losing the plot here... so between your google forum and this apple support, yes, I'm sure the issue is in this limit... ugh

Folks, just spent 6 hours with Google last week and now 1.5 hours with Apple yesterday 2/27). Did a screen share and they saw me purge on my iMac (10.13.3) cache in library for calendars as well as containers, then activate google apps calendar (form sys prefs / internet accounts as well as from inside the Calendar App) and watched the cache go from 600KB to 32.5MB, along the way, it was populating all items into my calendar... then as it stopped at 32.5MB, everything but one of my daily reoccurring items disappeared. They took the diagnostic info from that (145MB) and were handing it off to their senior tech guys... they know this is an issue after the updates on ~ Feb 17th or so. Something VERY interesting... when I export my calendar from google to my mac, after it's unzipped, it's 12.4MB... but Calendar Caches shows it at 32.5MB... so something is wrong with Calendar and it's inability to STOP syncing the data or sucking down MB of something from the google calendar on the cloud... I proved it was apple's issue with Google as we did delegation with a gmail (free) account I have and it's calendar. Took down the google calendar from the broken account... through delegation on the gmail calendar... no issues.... but that is not good, it's just a stop gap... Apple is to call me back today / tomorrow (Feb 28th / March 1st) after the techs go through the 145MB of sys log data and I'll update... this really stinks, but if we can fix it for others, then I guess karma will come our way 🙂

I called google after trying to fix for 2-3 days. They strongly told me it was an Apple problem. To prove it, my other google apps calendar works syncing with Apple. The broken one works with the google app. I add something to the google app and it populated my apple calendar. So using the google app till it’s fixed. I did ask if a google calendar item could be corrupt. They said it was not if it worked on the google calendar app. PIMA. Still broken. DO NOT use time machine to repopulate the calendar. Or do not export from calendar.google.com. It will resend ALL your your items going way back. One person received 250 invites for past items. Ughhhh. Waiting for google to respond to my request to see if data corrupt

yeah, that's what I thought... if it goes the distance, then blows up, there must be corruption in the Google DB

Yes. Data ***** down from google to Apple device. Shows up briefly. Then disappears. File still 41MB and calendar on Apple can read and show in calendar app
