I'm currently developing a game that uses multiplayer servers from PlayFab. For the month of September, I had no servers running or on standby. However yesterday (11/09/2021) apparently more than 740 instance hours were used up. The only thing I did was deleting some regions from my builds and setting the max servers parameter to 0. Does this cause instance hours to be used? And why so many?
Total usage also shows that there were no servers running.
