问题
When I tried to upload a bundle to the Alpha channel on the Google Play console it shows to me this warning:
The warning is shown after uploading mapping and native-debug-symbols files.
回答1:
This is probably due to a non uniform icon shape of your app:

You can change your icon according to the new design specifications to remove this warning.

I fixed the above warning by replacing the app icon (Playstore Icon) from the new Google Play Console>Main Store Listing>App icon based on the new guidelines introduced by Google https://developer.android.com/google-play/resources/icon-design-specifications To export the new Play Store Icon, i followed the below link https://developer.android.com/studio/write/image-asset-studio (Image Asset Studio places the icons in the proper locations in the res/mipmap-density/ directories. It also creates a 512 x 512 pixel image that's appropriate for the Google Play store.)
From Android Studio right click on the folder res>New>Image Asset
Generate the New Play Store Icon from the "Configure Image Asset" popup by selecting the Icon Type as Launcher Icons (Adaptive and Legacy) if your app supports Android 8.0 (https://developer.android.com/studio/write/image-asset-studio#create-adaptive) or select Launcher Icons (Legacy Only) if your app supports versions no higher than Android 7.1 (https://developer.android.com/studio/write/image-asset-studio#create-legacy)
Click Next and a new Popup appears to Confirm where to export the new Play Store icon (ic_launcher-playstore.png) (512x512).
Click Finish and upload the new exported Play Store icon in Google Play Console>Main Store Listing>App Icon and the warning now is gone.

Go to Google Play Console > "Main Store Listing" and see if your App Icon is meeting their standards.
Upload/replace with new App Icon 512px by 512px
For me this was the issue...
