The linked gmail calendar was suddenly no longer linked. Please help to fix this asap

Staff were repeatedly booking time slots for customers at times that were not available on my gmail calendar. When I addressed it with staff, they sent screen shot showing all time slots were available. The gmail calendar that was previously linked with the YCBM account is no longer linked. When I went to the YCBM account to fix this, it was impossible. The error message said “You must link to a writable calendar". What is a writable calendar? Please help me to fix this error asap. Thank you.

@drjarmstrong a writeable calendar is essentially a calendar with permissions setup so we can create events on it. It may be setup only to “read” which only allows us to check for free/busy time. For your setup if you are connecting to Team Members, I recommend to setup them up under Team Management (YouCanBook.me). You can invite them and then they will integrate their calendar directly with YCBM to ensure we have proper permissions. Also I checked on your pages and I do not see any errors, if you are still seeing issues, let me know.
