I can no longer create invoices through the mobile app (sales tax issues?)

Hello, Starting on Friday, March 15th, I can no longer add items to an invoice. When I go to add an item I get the usual "service date", but it now also requests a "tax rate". Even on non-taxable labor. I run a field copier service company in Greater Los Angeles area and there are hundreds of different tax rates here. In the past, QBO has always charged the appropriate tax rate by zip code. The mobile app didn't get it right, but if I saved the invoice, then re-opened it, it would reflect the correct tax. Now, it is asking for a tax for each item when I try to create an invoice in the field. If I try to select a tax to apply, it crashes and goes back to the login screen. This has rendered the app worthless for me. I can't even use it to look up pricing to hand write work orders.

I have also been unable to open, and edit invoices that were created on a desktop computer. I've already updated the app twice and also cleared the cache to no avail.

Anyone have a solution?
