Thanks, but this isn't working for me - partly due to my experimentation, no doubt, but there is a definite lack of configurability even after the update.

Somehow I've managed to delete my Google calendar from the Jolla (still exists on the server, all good), and neither disabling/renabling sync, nor even removing the account altogether and re-adding it to the device can cause it to re-appear.

The 'Manage calendars' dialogue is someone's idea of a joke, surely? All it allows you to do is enable/disable calendars (I think?) and - haha - choose what colour your calendar should be.

I don't want to do a device reset for something as ridiculous as this, but that's my only idea for now. I will see if any more brainwaves strike.
