Symphony Pro for iOS
When adding a stave (track) to an existing work with text, all the text disappears and you can't get it back with undo!
Thanks for reporting this. I don't think that there is any way to recover the text at the moment. It's possible that once this gets fixed your text will show up again, but it depends on the nature of the bug.
Thanks for your help, Ross.
I always keep a duplicate of my work, so nothing has been lost, yet anyway!
