Otterbox causing issues with touchID on iPhone 8

[Glmnet1]

My dad purchased a iPhone 8 and put it in an Otterbox Defender case. Now he says touchID doesn't work most of the time.

Does it happen to everyone using that case? Anything he could do to help?

Try re doing the Touch ID with the case on. Should fix the issue.

Sorry I forgot to mention, that was my first (and only) idea. He redid it twice but it's still not working.
