This has worked fine previously, however now when I attempt to log in, I receive the phone call and can here the message, but the key press is not registered and eventually the call hangs up and the connection closes.
This has worked fine up until around a week or so ago.
I have tried pressing different keys and also holding down the keypress for a few seconds but nothing registers.
A colleague can get this to work using a keypress from his android phone.
I am using an iphone 8 with IOS 12.2
