I'm recently getting a message on google play console that prevent publishing and updating my Qt android app. Google wants me to use Android App bundle but I'm not sure how to proceed. Does anyone know how to get around this issue?

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.
