Kato here, thanks so much for the feedback. We love hearing from developers, especially your criticisms. Feedback like yours has been a big part of shaping Firebase over the years. Do me a favor and please reach out to me directly with your project name and some details, and I'll see if we can do anything to help out here.
To make this perfectly clear, nobody monitoring this mailing list (i.e. the Firebase community) manages Google Play versions, testing, or release schedules. However, we do have a dependency on their service, so that doesn't excuse away our responsibility to review this failure and to do what we can to make sure it doesn't happen again.
It does mean that the rant isn't necessarily reaching the people with the most influence over that product. I'll do my best to forward this on and make sure they feel your pain here.
☼, Kato
P.S. If it's not offensive to your culture or beliefs, I'd encourage you to introduce yourself! We are a close-knit family. It's easier to keep that culture strong when we remember that there are real people on the other end of our emails. Getting to know one another by name is a great first step.
