I've got problems with existing Viber on Z3, so decided to reinstall it.
I've deleted it and downloaded newest .apk from Google Play (in case it's newer than from Amazon AppStore).
But that new Viber from Google Play didn't start (just disappears from the screen), so I've deleted it and am trying to install usual one from Amazon App Store. But it says "You have already installed Viber. Delete it first".
But I have no any Viber at the moment! How could I clear cash (or whatever else) and install Viber on my Z3?
Thank You!
