Hi everyone. If you are unable to change transition from anything but "Desolve" it is not because the board sizes are different, but rather because the "blue line" is placed at different heights. The blue line appears at "the fold" when you click the artboard. It controls the view size when you preview your boards. - Check if the blue lines are set at the same height for the two boards - If not, change to same height - You should now be able to choose between all transition types. Hope it helps! ... View more
