UPDATE: I’m hearing reports of calendar apps crashing quite severely. Please only experiment on non-vital apps as you could hypothetically lose data stored in them! But apparently if the app crashes and restarts don’t fix it: a forced restart will.

Proceed with caution, at your own risk, and report any findings!
