User is trying to integrate with QuickBooks Online, but gets the following error on entering the QuickBooks Online credentials:
You’re not a listed admin for this company.
This can happen if you are using a QuickBooks Online account that does not have admin privileges. The QuickBooks API only allows you to integrate accounts that have admin privileges. Contact your QuickBooks Online administrator to give you those privileges if you want to integrate your account with Core. Check the Core Help for more on Core-QuickBooks Online Integration.
