Welcome to the QuickBooks Community, @candy133.
I appreciate the efforts you exerted to fix the issue with creating estimates in the QuickBooks Online mobile app. I'd like to redirect you to the best support group available to get this address.
Since clearing the app's data and restarting the phone didn't fix the issue, I recommend contacting our QuickBooks Support Team. This way, they can further check on this matter and provide in-depth troubleshooting steps to get this resolved. They can also create an investigation ticket if other users are experiencing the same.
To reach them using your phone, you can follow the steps below:
- Sign in to your QBO account on the mobile app.
- Click the Question mark icon at the top-right corner.
- Choose Help and Support.
- Select Contact Us, then enter your issue and click Continue.
- Swipe down and tap Have us call you or Schedule appointment.
Just in case you want to make changes to your sales templates on your mobile app, you can check out this article for more guidance: Customize invoices on the QuickBooks Online mobile app.
Come back to this post if you have other concerns or follow-up questions about creating estimates in the QuickBooks mobile app. I'm always here to help.
