I am getting "The APK is signed with a different certificate. Be sure to use the same keystore and key as used for a previous version". I first got an error that I had it signed with V2 type of signature which is not compatible with the Oculus Go. So I've resigned it jarsigner tool. So yes I am using V1 signature now. I've asked Oculus support to remove the previously uploaded binary, but nothing is happening yet.
