Yes this seems to be a recurring issue, you should report it to Apple here: Feedback - iPhone - Apple
I can only unlock my iPhone 7 red with passcode after downloading IOS 11.1.1. I deleted all fingerprints, shut down phone, restarted phone, added new finger print. And I still cannot unlock my iPhone with Touch ID. I have to use passcode Has anyone else experienced this problem? Additionally, this new version i am experiencing a huge battery drain

The battery drain is "normal" due to extensive "housecleaning" of unnecessary old iOS code data - I have yet to have someone post back when I say, "If this persists beyond 24-48 hours, post back." 😉
