Thank you for joining the thread, @pncvision.
Allow me to help you with this and ensure you are able to login to your GoPayment app on your mobile device.
Since we don't have any reported cases about this issue, let's make sure first that you are on the most recent version of the GoPayment app available on the Play store.
The minimum supported version of GoPayment for Android is 4.1.1. If you are using version 4.1.0 or lower, you will not be able to login to GoPayment.
It's also possible that something may have occurred that damaged the GoPayment installation or its update. Completely uninstalling and reinstalling will solve this problem. You can refer to the link provided by my colleague on this thread for the detailed steps.
However, if you still can't log in, it'd be best to reach out to our Merchant Services Team so they can isolate this issue further. They have the necessary tools to check this in a secure environment.
Let me know if you have other questions about the GoPayment App. I'll be here to help.
