Hi, @amergs. I can see how important it is for you to add calendar appointments in your QuickBooks Online (QBO) mobile app.

- Select Search, then press the Contact Us button.
- Enter your question in the box and hit Continue.
- Choose the best way you'll want to reach out to us.
Please ensure to check their availability since they can only accommodate you Mondays to Fridays from 6 AM to 6 PM PT and Saturdays from 6 AM to 3 PM PT.
