Your Android App Bundle is signed with the wrong key. Ensure that your app bundle is signed with the correct signing key and try again

Question

How do I sign my android app bundle with the correct signing key?

Answer 1

I was banging my head on the table over this for about two hours. When I finally gave up and was filling out my "reset key" request, I realized that I was currently attempting to upload it to the wrong project the whole time.

So, step one: confirm that you're attempting to upload to the correct project.
