ClickUp Tasks which are then populated into Google Calendar as events are not two-way syncing. After the tasks have been populated into Google as events, I change the time and date of these events in Google. But after a while, about 10 minutes, the Google events revert back to the time and date that ClickUp tasks were originally set up with.
Please make ClickUp and Google Calendar integration full two-sync. I think it is deceptive that you advertise it as such but there have been bugs with it for years.
