Comment 67 for bug 1945368

Feedback:
Asking people to try using the calendar-data/backup 'local.v22.sqlite' file renamed as 'local.sqlite' to replace the 'local.sqlite' file stored in 'calendar-data' is not getting any of the calendar data to display.

I also have a report from one person that they do not have the calendar-data/backup folder.
