I created a key.jks file using the keytool, followed the instructions carefully from https://flutter.dev/docs/deployment/android and yet the error below repeats. Any ideas?
Upload failed You uploaded an APK that is not signed with the upload certificate. You must use the same certificate. The upload certificate has fingerprint: [ SHA1: D9:98:AB:A9:49:61:72:CE:FF:EA:77:7C:10:6D:1A:DF:34:B8:F5:5B ] and the certificate used to sign the APK that you uploaded have fingerprint: [ SHA1: A8:0D:00:CF:1A:00:11:6A:04:A0:7C:0F:FD:DF:BA:ED:55:26:27:C8 ]
Beware, as I uploaded an app in 2013 and downloaded it myself support could not delete the app, hence I created a new Google email account and paid again and uploaded it with a new key. This worked. So hold on to your key or pay again.
