I got enthused when I noticed that the default username has been implemented in mobile version 2.17. I looked up the version of Bitwarden on my iPad and it was 12.6.something. I visited the AppStore and it offered an update for Bitwarden which I accepted. But after the update my Bitwarden on my iPad is 12.6.4 and no option for a default username. How can I get version 12.7?
