What I did: Purchased Pro license through the web store, and tried to input my license key in the app through the Help menu.
What happened: There is no “Enter License Code” option, and both “Upgrade to Pro…” and “Restore Purchase…” take me to the App Store.
What I expected: To be able to enter my license code
