It gets worse! If Google decides the people in your test don't engage enough and/or you didn't respond to their feedback, they may not give you production access. I've got a game that's available on iOS, I released there first and did lots of testing to deal with the low-hanging bugs. After doing the 14 day test Google emailed me:

Possible reasons why your production access could not be granted include:

    - Testers were not engaged with your app during your closed test
    - You didn't follow testing best practices, which may include gathering and acting on user feedback through updates to your app
