After you have connected the Google Calendar to ACE Meetings, you will be prompted to select which calendar we should check for availability. Make sure to select your main calendar in this section so the meetings are set accordingly.
You can check what your main one is by going to Settings, then Calendars.
If you’ve decided to change your main calendar, or want to use a separate one, you can click on the drop-down menu to choose which calendar you want. After that, you can choose any calendar of your liking from that account, in the drop-down menu right under.
