How can we get our app bundle Sign in key. So, then wecan upload in Play console for key rest

Hi Median Support Team,

I need help recovering/obtaining the Android signing keystore for my existing app Brick Breaker RPG.

My original Median project was deleted, and I no longer have access to the original Android signing key. I have created a new Median project using the same app/source code and package name, but the new AAB is being rejected by Google Play because it is signed with a different certificate.

Google Play currently expects the following upload certificate:

SHA-1: E9:39:2A:54:99:6F:7E:B0:63:57:92:6B:21:6F:93:B1:F8:97:4F:C3

My new Median AAB is being signed with a different certificate:

SHA-1: E4:9F:E5:70:28:FC:BE:08:32:97:DC:8F:3B:D0:DA:5A:9D:6A:59:F8

I understand that Median uses a release signing key for Android builds. Could you please help me obtain the original release keystore/signing key associated with my app, or advise whether Median can configure my new Median project to use the appropriate signing key?

I need to resolve this signing mismatch so I can continue publishing updates to my existing Google Play app rather than creating a new application.

I would greatly appreciate your assistance.

Thank you.
