Fingerprint Authentication in the new SmartThings App? When?

Pretty sure I’m beating a dead horse here. Why do we not have fingerprint authentication as an option in the new app when the old one has it and works just fine? I like the secondary biometric requirement, yes the phone is locked with PIN and primarily fingerprint but I would like the SmartThings app to request again like my banking and credit apps do. The reason is primarily for my wifes phone whom I most concerned with losing or she loosens security because I have my door locks controlled in SmartThings which I like to take advantage of to let family, friends or neighbors in my house remotely without giving keys out. Since we are now being forced into the new app this should be included.
