Here are some things to check if it looks like some of your events are syncing, but not others
Were the missing events in the past at the time you created the sync?
CalendarBridge does not sync events that were in the past at the time of sync creation (except for recurring events that also extend into the future)
CalendarBridge does not make copies of copies
One thing to keep in mind is that we do not make copies of copies — events only ever go across 1 sync connection. So if you have only synced A -> B and B -> C, A events will not show up on C. To get A events on C requires a 3rd sync: A -> C.
Do any of your calendars need to be reconnected?
If we have lost access to one of your calendars (e.g., due to a password change) a red ‘x’ will appear next to the account on calendarbridge.com/dashboard/accounts (or, if the loss of access has persisted for long enough, you should have received an email). Here are the guides for reconnecting: reconnect a Google account, reconnect a Microsoft account.
If none of these seem to be the reason for your missing event copies, please submit a support request.
