i am not able to connect to proshop

I'll share some situations regarding your connection of the Proshop application to QuickBooks Online (QBO), Nina.

When you previously linked your ProShop app to QBO, did you use a third-party app connector? If so, I suggest reaching out to their support team for help with the reconnection.

Here's how to check their contact details:

1. Go to the left-hand menu and select Apps.
2. In the My Apps section under Overview, locate and click on the app you’ve integrated.
3. From the app information, you can check their support information.

Otherwise, you can contact ProShop to verify whether they still allow QBO integration.  

You can reach us again if you have additional questions related to QBO. We’re here to guide you.
