I purchased the "Apollo Lunar Missions" in app for SkySafari 6.8.0 on an iPhone 6s. The purchase was successful and shows as purchased in the app store. I am able to start the download to SkySafari but it never completes. Hitting "Restore Purchases" yields the same result.
I also purchased the "Interactive H-R Diagram", "PGC Extension Database" and "GAIA Extension Database". All three of these purchases installed successfully.
Any help would be appreciated.
Thanks,
Jeff
