iPad Air Intermitten TouchID Problems

[Lars96704]

Ipad Air 3rd Gen updated to 15.5
TouchID works one moment and then stop working. I have deleted and reset fingerprint several times. Is it the button, Ios update or what. Very frustrating.
thanks

Instead of deleting your old fingerprint, just add new ones.

Each time touch ID starts acting up, add another fingerprint, but, to the same finger that you normally use.
