SOLVED. After using the URLs that Danny recommended, I found that both apps are INCOMPATIBLE with my Samsung 5 device, running Android 4.4. I guess I'm behind the times. However -- in my opinion -- the Google Play Store should STILL show those apps when I do a search, but with a red X through them or something that indicates they are incompatible with my device. Perhaps there is a setting somewhere that controls this? If so, I don't know where that setting is but I would like to turn it on. Thanks to all for their help. --vincent
