Finger print recognition

[Redlac]

I've used my finger print to log into my S10+ since I got it last August and it has worked well until recently. I've now logged 3 fingerprints and can't get logged in with any of them. 

I've switched on the sensitivity and still can't get logged in.

@Redlac: What happens when you attempt to unlock the phone with your fingerprint? Do you get any error messages? Do you have a backup password enabled to bypass the biometrics? If you open the Samsung Members app and go to Get Help > Interactive Checks > Fingerprint, and follow the on screen instructions, does it return any errors?

No error message. Fingerprint number 2 is now working well. I've removed number 1 and tried to re-install, but it keeps telling me to press harder, I can't press any harder than I'm doing.
