Also have been having this issue since February. App updated on my phone, and have the exact same thing happen. My two co-workers have no issue, QBO App (android on all our work phones) looks like it did before on theirs. (one is new hire no admin, one is partner and co-admin). Their version allows setting the tax rate for the invoice as a whole, mine still asks for each item's rate, and crashes when I attempt to set it up.

Have had no issue like this from 2017-now.
