When you set up a daily schedule for your table, it will run every day regardless of your expected monthly cadence. To change this, you'll need to adjust your scheduling frequency:
1. Click the ⛭ icon on the top right of your table
2. Under "Run the table, " select "On a schedule"
3. Change the frequency from "Day" to "Month"
4. Click "Update Source Schedule"
This will ensure your roles are updated monthly rather than daily.
