Hello. I have a pro account.
I am unable to set up sync with google calendar.

I had synced it originally, but recently it doesn't seem to be working, so I tried to un-sync it and then re-sync it.
When I tried to sync them again, I got an error message saying "This app is blocked.
error message appeared and I could no longer sync.
If this function is not able to use no longer, I'd like to ask you to refund.
