IT WORKS!
Going into application rights, and validate all!
Fingerprint works after : apparently something was locked fingerprint...I try after to remove all rights....and the fingerprint continue to work!
Really strange...but works now
Hello
Same problem for me
Upgrade from Huawei mate 9 (with android N and updated to android O) to Samsung Note 8 (with android N)
Works correctly with the 2 android versions on the first device, and fingerprint unavailable on the second device
