Annoying! I can't sign in, I'm not receiving any notifications from the block ID app. No number is showing on the app to verify my account. The code Otp is useless. I can't even scan my own phone via desktop site😂 The only way to sign in is by having another phone, taking a photo of the QR and scan it from ur phone.

Very rubbish, I was not able to login easily. I already tried thrice to go through with tapping the right number and once it's said I was successfully login and once you go back to the site your accessing nothing happens and it's re-login page again. Like what's the sense of this? For inconvenience?
