You’re correct! I’m running the Release Candidate of 15 on a Dev profile, but was able to get the shortcuts to respond again after restarting my handset. Sorry about that…
Though on the subject, since iPhone users do not have the benefit of the keyboard shortcut guide/panel that appears when holding ⌘ on iPad, is there any way you could publish the contents of that panel for Drafts in a table format?
I will literally make it for you if you send me screenshots.
