I've a client that already had an app from another company.
The other company already enrolled for google play application signing to manage the keys.
I created an app like usually with my app.keystore, but like i suspected it gave an error:
"Upload failed Your Android App Bundle has been signed with the incorrect key. Please make sure App Bundle is signed with the correct signing key and try again: SHA1:..."
What's the problem here? it's not the point signing with google to manage the key so I don't need to provide one anymore?
I tried to upload .aab file or .apk.
What i need to do on my side to work? Or I can't do nothing? What can I do to make my .keystore valid? it should not mater if i upload the .aab right? I'm really lost.
Any help regarding on this aspect I would appreciate a lot.
