I am running SkySafari Pro 6.5.0 on a MacBook 6,1 with Mac OS 10.11.6. The Apollo Lunar Missions, PGG Extension DB, and GAIA Extension DB all say "Purchased" in Settings, In-app Purchases. I'm not sure if there is a need to "select" the DB extensions, but I can't figure out how to access the Apollo Lunar Missions. Restore Purchases makes me sign in to the App Store, but appears to have no other effect.
Am I missing something, or is the issue still pending resolution for my OS version?
