And inventory from Foodics to quickbooks, the Button “Manage” can’t see there and I can’t click even in the installed button as it is like idle

I want to ensure this is taken care of, @accounts271.

Usually, the error occurs when there's too much cache in your browser. To fix this, let's perform some browser troubleshooting steps. Let's start by opening QuickBooks Online (QBO) through an incognito window. It's the best place to identify web issues. Here are the keyboard shortcuts:

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

Try to see the Manage button again. If it works, go back to the regular browser and clear its cache. We advise customers to clear them out periodically to prevent and fix web issues. You can also try using a different browser. Here's the link: System requirements for QuickBooks Online.

If you still have the same error after following the recommended steps, use other supported browsers in QuickBooks Online.

I've added this link about tracking inventory in QBO: Set up and track your inventory.

Leave me ac comment below if you have other questions. I'm always here to help. Take care!
