Hi Vincent,
Thank you for reaching out regarding the SHA key mismatch while uploading your Android build.
The SHA-1 key is automatically generated during the build process and is registered with the Play Console when the app is first uploaded. This key is tied to the app’s bundle ID (package name) and remains unique to it as long as the app is live on the Play Store.
A mismatch typically occurs when the bundle ID is changed. In such cases, the Play Console cannot verify the new key against the previously registered one, leading to the error you encountered.
To avoid this, we strongly recommend not changing the bundle ID once an app build has been uploaded. If you are migrating an existing live app to the AppMySite platform, make sure to add the original Keystore details during the build process to retain the associated SHA key.
