Few remarks while testing the feature , in this context Bob is the owner (sharer), Alice is the receiver of the share :

• When Alice quits the share, it doesn't update for Bob
• Bob Unshares, doesn't delete for Alice
• can't toggle edit permissions for federated shares
• Alice doesn't see events from shared the calendar
• Alice can't create events on the shared Calendar

I checked out both calendar and server Prs

Just to double check, did you checkout out both PR's on both instances?

Okay, apologies, found the issue, I accidentally didn't push the calendar settings change, fun of working on two instances at the same time...

Notes from Yesterday's test:

• Sharing, Editing privileges, read, Edit: work as expected ✅
• Quitting a share, Unsharing -> don't update for the other user 🚫 (Can be fixed in a followup )
• When running sync command with one of the received shared calendars being unshared from the owner (doesn't update because of Point 2 👆🏼)

Failed to sync calendar f98f0703147a5feeb0180ca9351b1783: Client error: `REPORT http://nextcloud.local/remote.php/dav/remote-calendars/YWRtaW5AaHR0cDovL3N0YWJsZTMzLmxvY2Fs/federated_shared_by_admin` resulted in a `401 Unauthorized` response:
