The Quickbooks phone app only has a constant VAT rate glitch where it assigns three vat rates instead of one each time. Any fix for this? Been like this for months

Thank you for posting here on the Community, userbrothers . 

Make sure that your mobile app and phone's operating system is updated. Then, you can clear app data. 

Here's how:

iOS

1. Go to Menu ☰ and tap Help & Feedback.
2. Tap Refresh Data.
   Note: A message appears “Caution. If there was a problem getting your latest QuickBooks Online data, you can refresh it now. It may take a few minutes.”
3. Tap Refresh to confirm.

Android

1. Go to Menu ☰ then tap More Options ⋮.
2. Tap Settings then Refresh Data.
3. Tap YES to confirm.

If the issue persists, we'll have to uninstall and reinstall the QBO application. Here's a quick guide to do it, or visit the link here to reinstall the app directly. Just scroll down to the Get the QuickBooks Mac or Windows App section, then click the Free Download button.

Post here again if you have other concerns with the program. I'll be right here if you need further assistance. Have a nice day!
