This is a change that has been implemented to improve the security of the connection between KeyPay and QuickBooks Online.
At this time, we suggest you keep tapping Switch Admin every time you're prompted.

Thank you for joining the thread, @nludlow.
If you've clicked on the No, Thanks button, it means that you don't allow KeyPay to view and update your QuickBooks Online data. Since the master admin user can no longer access payroll, I recommend reaching out to our Support Team. This way, they'll be able to check and verify the status of the user as well as the connection between KeyPay and QuickBooks Online (QBO).
To contact support, you can follow on the steps provided by Ryan_M above or you can check it here: Contact the QuickBooks Online Customer Support team.
