A future version of the app will stop the backspace button from also functioning as a "back" button. The change has already been rolled out in some experimental versions of the app, and has upset some users. Developers have said that the feature is only being partly enabled for now, in case there is "sufficient outcry" and it needs to be rolled back. People regularly press the button thinking that they're deleting a word from a form, developers said, but then find that they weren't actually typing into that form and so accidentally go back, losing everything they've done.
