my Dad's phone was lost during hospital transfers. we got him a new phone number. after several tries and we finally managed to change his phone number in singpass. unfortunately, the singpass went haywire and the OTP page is missing from his singpass account, only left with the damn face verification which keeps denying my Dad from entering. very pak cek, the face verification page doesnt work, keep jumping to ' camera not detected screen'. and OTP page missing. Called singpass to resolve. Took a month to resolve. face verification page still there.
