Bug calendar change and appointment modifications

Hello,

I have detected a bug related to the Google Calendar integration. We recently changed the calendar we use in Google (switched in Bookingpress for a user from one Google Calendar to another, but still within the same account). After this change, it is no longer possible to update or cancel any appointments that were created using the previous calendar integration. This is causing several issues, as it affects both past and future appointments linked to the old calendar. The only error message shown is a generic "something went wrong".

As a temporary solution, I switched back to the old calendar to make the necessary changes, then switched again to the new one. However, this workaround is very inconvenient and not a sustainable solution—it also took me quite some time to identify the root of the problem.

Best regards,
