FaceID or PIN access to mobile App

Good evening, is FaceID or a short PIN a possible option for signing on to the mobile app?

Yes, click the Garadget logo in the mobile app and then switch on “Authenticate” to enable the pin.

Y had tried with both method on iPhone X. I had to delete the app and re-download it

If anyone wants to participate in beta testing of the new version of iOS app, please PM me your apple ID email and I’ll send the invite.
