Why won't fingerprint sensor work on some apps on my Xiaomi Redmi 4?

Hello all, I have a concern. The fingerprint sensor on my phone does not work for apps like EBay (opening app) and PayTM (checking passbook). The sensor works perfectly for other functions like unlocking devices, capturing pics, etc. However, this usage of FPS is supposed to be available in all phones. Am I missing something or is this normal behavior?

Example - I had a Moto G4 Plus before this. In it, I could use the FPS to lock my passbook in PayTM (feature of app). 

Hi Akshit Baunthiyal. Can you try to clear the lockscreen lock and try to enter a new set of fingerprint? Please let us know if that makes FPS work on other apps.
