How to fix Google oauth verification error

Question

When I sent my application to Google oauth team, they said it's a developing or staging application and these are not allowed for oauth login. And the thing is I already published my application a month ago. And also added a download button for it on my website Here is a pic- What they mailed me

Answer 1

I am pretty sure the email/reply itself is self-explanatory. "Google" thinks that your application itself is not complete and is still in development. Please try to contact google support team regarding this. That is all I can say from the amount of information you have given.
