Good app but add-ons need work – SkySafari 6 Pro Review

I have had this for many years including early versions and it is a really good app, but ran into a problem after deciding to purchase two database extensions, galaxies and the GAIA catalogs. I received notice of these add-ons while using SS Pro and decided to purchase both. After the purchase was completed, I did not receive any instruction or notice about the add-ons from SS, therefore I assumed then that they would be installed when I used the app, however I was not sure if it was updated. Assuming that it had been updated, I received a notice that there was a free Apollo 11 add-on and downloaded it. Same thing, there were no instructions or notice that it had been installed. After that I suspected that something else needed to be done and found them listed in the settings to be installed. The problem here is that there is no method of selecting an individual add-on to be installed. If you tap the add-on it will ask you if you wish to purchase it? When you press Restore Purchases on the bottom it will begin to install all apps. It failed to install all of the apps the first attempt. I decided to try again and instead of installing the just the app or apps that had not been installed on previous attempt it begins all over again, that is reinstalling all add-ons. The GAIA add-on is the largest and after two attempts unable to install it even after freeing up memory for it, but the frustrating thing is that you have to wait until it reinstalls all of them before knowing if it successfully installed that one. The Apollo 11 add-on was interesting, but it indicated that there is a View Missions button, however there is no button. You click on the View Missions text in the settings. I still think this is one of the best astronomy apps available, but instructions were lacking concerning add-ons and there should be a way to select an add-on for installation rather than reinstalling all of them.
