Album files

My Linux laptop has updated Musescore to v3, looks really good. However, 2 things I used to do, do not seem possible now;

1) create an album file to join 2 tunes together and produce a single score - my album files do not seem to be recognised by Musescore now

2) change text in a Volta from a right click on the object (I can do this from the edit element panel though)

Or maybe I am now looking in the wrong place in the v3 menus...?
