The issue you are facing:
A user tried importing a Google Calendar that had a ‘/’ in the calendar name. We dropped the ‘/’ in Google and reran the import. It came through as a new calendar but the original import is still showing as spinning and attempting to import on the Calendar page. We cannot figure out how to stop the process. Any thoughts on stopping the processing for the end user?
Is this the first time you’ve seen this error? (Y/N): Y
Steps to replicate it:
- Import a Google Calendar with a ‘/’ in the name.
- It will spin and never load the calendar.
- It will not stop trying to load the calendar even after logging out and back in as the user or dropping the migration account and re-adding it.
