We have a few apps published in Google Play, all are signed with same keystore. Last year we switched to app bundles, enabled signing by Google Play. Everything works fine when signing and uploading bundle manually. Although when I tried uploading bundle to Google Play via fastlane it gives me an error:
Google Api Error: apkNotificationMessageKeyBundleSignedWithWrongKey: The Android App Bundle was signed with the wrong key. Found: SHA1:...., expected: SHA1:......
If I upload same .aab manually, everything is fine. What should I do? I suppose something from Google Play signing. I don't want to break anything since I'm only a developer and not account owner. Can I generate new keystore without breaking existing?
Edit: on App Signing tab in Google console I can download upload_cert.der and deployment_cert.der
