While trying to update state in Company address, get this msg: An application error has occurred while processing your request : -90. Initially trying to set up Sales Tx

There are no open investigations similar to yours upon checking our records, lshulda41.

The error can be caused by too much cache. Let's perform some basic troubleshooting to fix it. We'll start logging into your account through an incognito window. It's the best place to isolate web issues. Here are the shortcut keys:

• Google Chrome: press Ctrl + Shift + N 
• Mozilla Firefox: press Ctrl + Shift + P
• Safari: press Command + Shift + N

If you're able to set up the sales tax feature, go back to the original browser, and clear its cache. It'll help you start fresh.

Also, you can use a different browser to help us narrow the cause of this behavior.

Let me share the reference about our sales tax to guide you better: Set up and use automated sales tax in QuickBooks Online.

This did not work for me. "Error has occurred message comes up after I input a random service/product and its price and the error message occurs when it auto totals the amount. Also, by the tax section to the left, a round 'waiting' signals keeps circulating, as if I am waiting for it to load. Why? My internet strength is at max. Thanks. 

Thanks for following the troubleshooting steps above, @newwavepoolsny-g.
