Bad and useless app forever…every second it has new problems sometime. It can’t scan the QR code. Sometimes it ask for registration. Sometimes it’s not working with the registration and also not working with a continue as a guest the useless app ever it takes your lots of Internet data and it’s always cracking you. If you scan one time so by chance your phone is dead or your phone is broken so you can’t scan same QR code with another phone first you have to delete that from the dead phone. However then you can scan this is the worst thing ever I hate this app swear by God
