Hi there, @user97551.
Welcome to the Community. I can share some troubleshooting steps so you can find the products when creating an invoice in QuickBooks.
You should be able to locate the items under the Product/Service column. We can use a private browser to open your account and see if the products show up. It doesn't use the cache, which stores data that creates browser-related issues.
Use these keyboard shortcuts depending on the browser you're using:
If you can see the products, let's switch back to the regular browser and clear its cache & historical data. This helps to restore the default setup of the browser.
In case private browsing doesn't work, I suggest using another supported web engine to get the best and most secure experience with the program.
I've also attached an article you can use to learn more about entering invoices in QuickBooks: Create invoices in QuickBooks Online.
You're always welcome to post any questions you have in this space. I'll be happy to help you some more. Have a good day.
Thanks a lot for your help
So i did a test
on google chrome it works, on iphone with the QB it works too.
However, when using, on the same laptop, the QB application (instead using google chrome), here we have the bug. I don't know how to "clear the cache" of this app ?
