Follow up from #519 (comment)

the first time a new user connecting calender, always got the below error and it didn't connect the calender. But it worked second time.

Error: Could not find any writable calender

This issue was fixed using this issue #588:

• when user connects calendar the first time, it could take time for Nulas to sync, that's why we get this error that calendar is not found
• so the solution implemented in this ticket [$150] Show syncing message and wait if calendar is not yet synced when scheduling interview #588 is:
  • when we connect calendar but we cannot find it, we still act as calendar was found
  • during scheduling interview we are checking if there calendar fully connect:
    • if calendar was already connected, then just schedule interview
    • if it happens that calendar was not yet fully synced, we are waiting until it's synced in Nylas for 2 minutes
      • in case it got synced during 2 minutes, we continue to schedule interview
      • if even after waiting for 2 minutes calendar is not synced, there is a big chance that something went wrong, so we are showing error message and suggest customer to reconnect calendar
