Hi there, dorothysworld.
If all of your clients followed the recommended troubleshooting steps above, and still getting the error, then I suggest reaching out to QuickBooks Support Team. They have more tools to initiate a screen-sharing session and look into this further.
Here's how to reach them:
- Sign in to your QBO account.
- Go to Help (?) at the top right and select Contact Us.
- Enter your concern in the What can we help you with? field and click on Let's talk.
- Choose either Get a callback or Start Messaging.
Leave a comment below if you have any follow-ups or other concerns. I'll be here to help. Have a good day.
