Google Calendar Syncing issue

I’ve tried setting up the Google Calendar sync integration but keep getting this error… and the all-day events won’t sync over. Doesn’t give me any more context than this. Any suggestions?

It looks like the error is being triggered by a specific event on 3/11/2026. The error message shows Fibery receiving identical start and end dates for that entry, but Fibery expects the start to be strictly before the end.

Do you have anything on your Google calendar on that date that was imported or synced from outside of Google calendar (Outlook, a scheduling tool, Apple calendar, etc)? It may not be following Google’s usual format which is tripping up the sync.
