Hello.

I'm having problems signing with United Airlines' iOS app with my enrolled face ID in iPhone's iOS v17.3.1. I even tried rebooting iPhone, uninstalling, redownloading, and reinstalling United Airlines' iOS app v4.1.104, but it didn't work. I did tell United Airlines iOS app to enroll with my Face ID when it asked "Face ID enrollment -- Would you like to sign into your MileagePlus(R) account using Face ID? You can always change your mind by going to the Settings menu in the United app." at log in App's Face ID settings screen show "Booking your travel" enabled. Where's the sign in part?

I signed out to get its log in screen, but got no Face ID login! I have to sign in manually with my MileagePlus # and password, and it still asked me to enroll Face ID or not. I told it yes several times.

Also, I checked my iPhone 12 mini's iOS v17.3.1's Face ID & Passcode -> Other Apps. I don't even see United app listed. Am I missing something?

Thank you for reading and hopefully answering soon.
