You can’t log out

Very annoying that you can’t log out of this app! My young son does not have a phone so I need to be able to log out of one account and into another to show our certificates. This app has no log out feature so you can’t do that. Even after permanently deleting the app after reinstalling it still is logged in and no option to log out and log in as a different user.

This app needs some work!

This app needs some work, the synch for dive logs with Shearwater Peregrine computers downloads fully according to the app however, they are nowhere to be found in the log function once downloaded. Very frustrating guys!
