fingerprint sign on doesn't work

[dualsport]

trouble with MY Shaw app,   fingerprint sign on does nothing, going to the manual it uses old info and I can't change so MY App is useless.  How do I recover it so it works with fingerprint sign on and I now want to change the email sign on, and password.  I did this on line app doesn't work

@dualsport -- what happens if you delete the app, restart your device, and reinstall the app? Does it ask for all the personal details?
