This literally doesn't answer the question at all. It's just a snarky remark from someone who seems to think everyone else should be as privy to how all this works as they are.
The man dev quit the project and others are picking up the pieces. They might not have access to the Play Store account, or maybe they do. Either way, the new team has not produced a new final version yet. Just a string of alphas and betas. As of now the beta is the main version. It's good enough for daily use.
You need to work on how you ask for things... This isn't my product and I don't work for you.
I don't know if this is news to you, but the "then" on the end of your statement has some sharp edges on it and represents you as entitled (making you aware if that wasn't your intention)
A little more grace goes a long way when you're asking strangers for help on the internet, friend.
