Yes, that was exactly what happened to me and what I meant when I said it was busted after a while.
does this still work?
Wait a couple of days more. I installed it on 12 April, the same day it was released. But yesterday, whenever I try to launch the app, it will open the google play store app and take you to the app page.
I think inside the app there is a self check whether the app somehow has been changed/altered. Maybe it checks the signature of the app.
Yes, it does works. just uninstall and re-install again.
