If I choose a "class" when reviewing receipts QBO not recognizing that I have done so, gives an error message "no class chosen" anyone know why? worked before...

Hi weinbergsfood.

Having your QuickBooks Online work the way it was intended is one of the things we focus on so you can continue to save time and effort. I'd be happy to help you with getting your class search working.

When QuickBooks Online isn't working properly it can be due to your browsers health. To fix this you'll need to clear your cache and cookies by following the steps in this article. Once you clear the cache and cookies you'll need to restart your internet browser for it to take effect. Once that's done it's also recommended to try opening QuickBooks Online in a private browser such as Google Chromes Incognito mode.

If this doesn't work I recommend contacting our support team for further assistance to get this resolved. You can reach them using one of the following methods:

Schedule a Callback or start a Chat: click (?)Help in the upper right in QuickBooks Online > type and enter "Contact support" into the QB Assistant > click Contact Us > explain your situation > click Let's Talk > choose Get a callback or Start a Chat.
Social Media: Facebook, Twitter, and Instagram.
Support hours are from Monday to Friday between 9 a.m. and 8 p.m. ET.

Have a great day!
