Musescore Songbook

I’m very confused about how the MuseScore app works with music I have created in MS 2.0. I’m sorry to say I’m not sure how I got the music into the player, but it’s in there and plays properly. The features all work except for the transposition. It simply will not work. When I change the key, the music flashes once and the new chosen key appears in the “change key/tempo” window, but the score doesn’t respond. Can you help, please?

P.S. The email response to my request for help suggested I include the file that Is not working, but I cant find the file on my iPad and can’t upload it now. Sorry.
