At your suggestion, I went to one of our products and found the Tax status was not set to “Taxable.” After changing it to Taxable, the tax showed up. Great!
Here’s a screen shot of the cart for this product at this point..

However, just a few minutes later I tested the product again, and this time the tax was missing again (screen shot below):

I checked to be sure the tax status is still set at taxable and it is. I’ve no idea why the tax display worked once and then reverted to not working (showing 0 tax).
If I’m able to get this working, will I have to go through all the products to set the tax status at taxable?
Thanks for your assistance.
