What I did:
  • Create an Android build, give it "version code" 13
  • Wait for the build
  • Download the build and upload to Google Play Console
  • Get error message "You need to use a different version code for your APK or Android App Bundle because you already have one with version code 12."
I just created this build with version 13 and downloaded it twice, but the the Play Store still gives that error. It looks like the build service isn't giving me the right download? Maybe it's still giving me the previous version? Several times I've had to built twice on Android just to get past this error.
