I created a Flow ( trigger: When an event is added, updated or deleted (V3) ) that listens for Events made to my Calendar from MS Bookings.
When I book an appointment through MS Bookings, I set the time-zone to EST; the email I receive and the Calendar event are both set to the correct EST time.
The problem is that when the Flow receives the data from the Event, the time-zone is off by 4 hours. It appears that UTC time is being used instead of the EST that I have configured.
The account context that the Flow runs under has the time-zone set to EST.
Although not really relevant, the Dynamics account I log into to see the data is set to EST.
