Thank for joining the Community family. I'd be happy to help share some troubleshooting steps to see your client list under Your Practice.
You may experience this type of issue when there’s too much data stored in your browser. It should not affect the client's list when you activated ProConnect.
To check if this is a browser-related issue, let's try to sign in to QuickBooks using a private browser.
Please refer to these keyboard shortcuts based on the browser you're using.
Press Ctrl + Shift + N keys on your keyboard (Google Chrome)
Press Ctrl + Shift + P keys on your keyboard (Firefox or Internet Explorer)
Press Control + Option + P keys on your keyboard (Safari)
If you're able to see the clients, you need to clear the temporary Internet files/cache in your regular browser. This helps refresh your browser and clear old files that it may try to use which can cause the display or access issues.
After that, try again to log in to QuickBooks to see if you can view your client list under Your Practice.
If you get the same result, I recommend reaching out to our phone support. They have the tools to check your account and can run the screen sharing tool to check what's causing this and get this resolved.
