Doesnt work as promised

I bought and installed the application. Firstly, no application shown, even the one in Extra.
Then, i found on internet that if you install first the 1.2.2 and remove it and reinstall the latest application from the appstore, the issue is solved.
True, now i can see the applications, but notifications dont work.

This is just too complicated…it should work from scratch, and as explained in the description
