I can't use my fingerprint as my lockscreen

[AC Question]

I went on youtube to figure out what was the problem and I cleared the cache and data and it didn't work and it would tell me that to restart my phone and it still doesn't do anything how can I fix this

What are you using as a lock at the moment? What device? https://forums.androidcentral.com/showthread.php?t=409154
