I've submitted a ticket to Canvas, no response yet.  Some parent/observer users in our school district receive the message in their parent app on their calendar with a red exclamation mark and the message "There was an error loading events.  Pull to refresh to try again."  I am also experiencing this issue.  The calendar events appear just fine in the web version.  We have tried the following:

1. Logged out/in to the app
2. Uninstalled/reinstalled the app
3. Rebooted the device
4. Verified the iOS up to date
5. Unpaired with student/re-paired with student

Nothing seems to resolve the issue.  Any help or advice would be appreciated.

THANK YOU!
