Why am I not able to set up my Touch ID on iOS 9 Beta?

[iMore Question]

I have updated my iPhone 5S to iOS 9 Beta version, and suddenly my Touch ID option has gone. I wanted to set it up again, but am unable to as it says 'Unable to setup Touch ID'. I have tried rebooting the phone, and resetting phone setting too.mdoesnt help! Anyone with a similar problem?

First... Go into settings and turn off TouchID.., reboot the phone... Then turn it back on... If that doesn't work, try reinstalling the iOS... If that doesn't work, it could be you've developed a haradware issue that will need service.

Because it's a beta. I removed it for this very reason

Is this issue only affecting the iPhone 5S or something? TouchID has worked for me on my iPhone 6 Plus no matter what iOS version I've had installed and it's still working without a problem.
