Existing app needs to convert to Google Play App Signing (AAB requirement)

Hi Median team,

We have an existing Android app that's been live on Google Play for years (package com.customchurchapps.appazzfb19a, 5,000+ installs). We recently need to publish an Android App Bundle to meet Google's upcoming target API level requirement, but Play Console is telling us we need to enroll in Play App Signing first.

Per your documentation on Android App Bundles, we understand Median holds the original release key for apps built through your platform, and that converting an existing app to Google Play Signing is something your team can help with directly.

Could someone help us:

Convert this app to Google Play App Signing using our original keystore
Set us up with a new "upload key" going forward, and provide the certificate so we can register it with Google

Our app's manage link: median.co/app/3n3cyv7u920pj85zw8nxkrh2xr/build

We're not currently on a support plan, but this is time-sensitive given Google's deadline. Any help you can offer would be greatly appreciated.

Thank you!
