Authentication Required - after trying to download a published game

EDIT: Indeed, if I go to google play thru browser it says that all my devices are incompatible even though the uploaded APK says to be compatible with more than 8000 devices. Below is my AndroidManifest.xml

I have been developing for android for almost 3 years now. This is the first time I made a game using unity. Everything went smooth and I finally published my game today. However, after trying to download the game from Play Store I always get "Authentication is required" warning from google play and there is no way from me to download the game. I can normally download anything else from the store. I can run the game if I sideload the APK. I am pretty much stuck because I have no idea how to fix it. Even if I build a new APK there is no way for me to test it if the game is going to be downloadable after I publish it on Google Play. I did add some plugins, which I know are changing the manifest file (permissions etc.). I am starting to think that there is something in the manifest that is making my device incompatible even though I am using Samsung Galaxy S5 (KitKat). If anyone had a similar issue or any ideas of what I could do please help. It would be much appreciated!

I'm having the same exact issue, and I have no clue what's causing this...

 

I think I found what was causing the problem. How big is your APK?

 

Hi everyone I am getting the same error "Authentication is required. You need to sign into your google account". And my apk is 20 mb. It was published yesterday I don't know what is happening.

 

What was the problem?

 

My problem was fixed, google have said me that it was a problem with its server.

 

Well, oddly enough, mine was a real problem. I had graphic options changed to OpenGL Es or something like that somehow, after changing that to automatic and reposting, it was fixed.
