If you're going to take people's money on the promise of giving them access to sheet music, then you really need to be giving RELIABLE access to sheet music. Roughly 60% of my playing experience using Musescore is ruined by coming up against a blank page with a little blue box containing a little question mark. Imagine being halfway through the second movement of a Beethoven piano sonata and having to stop your beautiful journey because of a blank page. And the 'customer service' is non existent. Stay away.
