Hi, @gpl1. 

Once this issue will get resolved, you have to link your invoices to their respective projects. I’ll show you the steps to link your invoice to the project. 

 Here’s how to link an open invoice:

1. Go to the Magnifying icon.
2. Click the Open Invoice.
3. In the Customer section, then select the Project you want to link.
4. Click Save, once done.

Also, you need to contact the customer support team so that you’ll get notified about the updates on this issue. I’ll show you the steps to contact them.

Here’s how:

1. Sign in to your QuickBooks Online company.

 2. Select Help (?) at the top right.

 3. Select Contact Us to connect with a live support agent.

 Please see this article to guide you on your invoices: Set up and use the Projects feature.

I appreciate your patience while our engineers are working for the permanent fix. Take care.
