already owning a full-version of Accordance 12, I wanted to switch to the Mac App Store version. However, I got stuck with the Lite version, not able to upgrade to full, without an in-app purchase.
How can I tell the MAS version, that I already own the full version, without a prior MAS version installed?
Is there a tutorial to switch from the Website-version to the MAS-version?
Any help appreciated!
