First, Google Play Store has disappeared from my apps. I find it with Google search and search for the apps I want. I go through install, etc. But then can't find them anywhere on my phone. They aren't listed in my Apps anywhere. But when I go back to Play Store and search for that app - it says "installed". This started a month or so ago. I had uninstalled Facebook messenger, but then saw that there was a PM I really needed to see. I go through the Facebook link to get Messenger and it never works. Facebook keeps telling me I need to install it. But when I go through Play Store, it says it is installed. Somehow around that time is when I lost the icon for Play store. Now I have a FitBit that I really need to link with my phone and having the same issue.
