First teething issue with the app has come up:
If you set the starting / ending fret for a chord other than the default (nut / 5th fret), then this breaks the app. The chord won’t look right on the screen, and then if you save the chart, you can’t get back into it.
I’ll be fixing this issue today and submitting the fix for Apple to approve. Sometimes Apple can take a few days (or even a week) to approve updates, which I understand will be quite inconvenient.
Thanks for your patience everyone, and thanks again for all the great feedback on the app I’ve been getting.
I’ve now submitted the fix to Apple, so hopefully they will approve it soon.
