Validation failed tax classification feature is not supported. Try again without tax classification error - Android app only - does anyone know how to fix it ?

Hi, I'm having the following issue on my android tablet.  Both the app and tablet are up to date, I did clear all data, i did uninstall and reinstalled the app too.  Steps to reproduce the issue:  1. Select 'Invoice' from the screen  2. Click on the little + icon to add an invoice  3. Select customer  4. Click on 'Add product or service'  5. Click on the green button 'Add product or service'  6. Try to add a new product, set name and price  7. Click 'Add'  8. Error appears - 'Validation failed Tax classification feature is not supported. Try again without tax classification code.  Note - When I tried to click on 'Select a tax code' nothing popped up, it looks like a dropdown/text field but it's not responding.  We never had this issue before. I checked that we have a standard tax rate set up as a default.  This flow works fine on a computer, the issue is on our Android app.  Quickbooks Online Version 29.37.0+1 (1592937001)  Android version 15
