I've purchased the Smart Tags and I'm eager to use them, but I go to the play store, hit install. In play, it says, "installed", though it doesn't give the option to "open" the app. The app also does not show in the app drawer or on desktop. I've removed and reinstalled, yet it refuses to be shown. I've looked in my file Explorer, "ES Explorer", and it can't be seen there after I do a search. Weird! Anyone experience this???
