Thanks for bringing this up, @bcshvac. Regaining the ability to view invoice details through the Profit and Loss by Location report is essential, and I’m here to guide you through the troubleshooting process so you can get back on track.
To begin, please refresh the page by clicking the reload icon in your browser or pressing F5 (on Windows) or Command-R (on Mac). This action will renew your session and help ensure everything operates properly. After that, check if you can access the invoices in the report.

If reloading the window doesn't fix it, please sign out of your QuickBooks Online account completely. Wait a few moments, then reconnect by signing back in.
Alternatively, I recommend clearing your browser's cache to access the program with a clean slate. You can also switch to other supported browsers for better compatibility.

Please let me know how these steps work for you. My priority is to help you resolve this issue so you can view your invoice details without any problems. If you have any further questions, feel free to reply below. I'm here to assist you. Take care.
