Default Expo App Icon showing with SDK 24 exp build Android

Hi,

Just upgraded to Expo SDK 24, followed all guidelines and even made by png icon to 1024x1024 instead of the original 256x256. But in both cases once I build with the following:

exp build:android --release-channel prod-v4

and I generate an APK, then once I install it on Genymotion simulator or BrowserStack App live the Expo icon is showing up instead of my own icon. This was never the case with earlier builds and sdk. I have all of the latest versions of the tools including exp.

Could you please help urgently because it is stopping a major release of ours.

Best,
Karan
