My android app is released in google play console and i have previously had no issue getting my apk deployed. I recently tried to update the apk and found that google play console will not allow me to release any further APK to production. Google message is

Warning "Unoptimised APK"

This APK results in unused code and resources being sent to users. Your app could be smaller if you used the Android App Bundle. By not optimizing your app for device configurations, your app is larger to download and install on users' devices than it needs to be. Larger apps see lower install success rates and take up storage on users' devices.

Use the Android App Bundle to automatically optimize for device configurations, or manage it yourself with multiple APKs.

Can anyone advise on how I might proceed? Is it possible to take my apk and use android app bundle to produce the desired format or is it something that has to be addressed in the qtdeployment tool?
