RequestSignature success when application will enter background

[pykaso]

When the biometry prompt is displayed and the application will enter background with a swipe gesture method PowerAuthSDK.sharedInstance().requestSignature(..) will succeed and return the wrong authorization header.

Expected behavior: Method will throw a Error

Probably a duplicate of issue #9

Could you please put break-point to PA2Keychain.m#L175 and let us know what is in s variable?

[pykaso]

FaceID/TouchID dialog canceled by swipe (switch to another application):

(OSStatus) s = -25293

Upcoming release 1.7.5 will provide a proper workaround in form of enhanced authenticateUsingBiometry() method. The method fully handle all such situations internally.

The issue will be properly resolved in future 1.8.x release, by introducing asynchronous API for signature calculations (see #497)

Our updated documentation provides a temporary workaround for this issue.
