Error From Start – Google Pay (old app) Review

Installed the app. Clicked on the app icon from home screen. The app opens to splash screen then gives an error message box stating session expired you will need to login again, with the only button being a signin button. Click the button, shows splash screen then the same message box pops up again. Spent hours troubleshooting it myself. Spent over 45 minutes on the phone with Google for them to say need to get Apple on the phone to verify compatibility. Only comparability requirement is iOS 10.0 or better; my device is an iPhone 8 w/iOS 12.4.
