I can help you set up the mobile reader users in QuickBooks, @kristimich.
It could be that you add the users to the GoPayment section. Thus, the users show a user for the desktop.
If you're using QuickBooks Online in a web browser, here's how to add a user for payments.
- Go to the Settings ⚙ menu and then choose Manage Users.
- Click Add user.
- Choose the Take payments only role and then click Next.
- Select the types of transactions the user can view and then choose Next.
- Enter the user’s name and email.
- When you're done, click Save.
