Hello I wanted to upload the new version of my application to the Play Store using Mobile Deployment, just like I've been doing for the past 3 months without any issues. Yesterday, when I tried to upload it, I received an error message that said, "Google Play failed to upload artifacts. The Android App Bundle was signed with the wrong key. Found: SHA1: XX:XX:XX...." I don't understand why this has never happened before, and I've been searching for a solution without success. I'm very sad.
Could you please help me resolve this step by step?
