It should be a rule in every company "don't blame the user"; if they don't contact you with their problems, it's _your_ task to let them contact you. Put a big "contact" button in your app, make it easier to give them direct feedback to you instead of in the app store.

And, obviously, don't release software that's not ready for production. The mindset "we'll just release without proper testing, the users will point out the bugs" - is so 1995
