Hi rjmaloney85,
Did you mean you can’t sign in SFB mobile app on your windows phone? Because there is no issue with Android device, it may be a client issue.
Regarding this issue, please try the following troubleshooting steps:
1. Update the system of your mobile device to latest as well as your SFB mobile client.
2. Please try to use another normal windows phone test if there is the same issue.
3. Try to reinstall the SFB application on your mobile device.
Hope this method is helpful to you.
Regards,
Alice Wang
