Currently, we do not have flexible meetings to adjust for DST, all meetings are tied to UTC. To adjust for this, you will need to go to the next instance of your recurring meeting to change it by an hour. For example, if your next meeting is set to 13 Mar 2023 for 10AM but you now need to adjust it to 9AM, you will need to make this change before 9AM on the 13th. Otherwise, you will get an error that states you can't change a meeting that occurred in the past.
