need help i publish 1 app and did not go well

i did publish 1 app im still lerning how to use the program.

the app is up on the store but the size on the screen did not adapt the screen it show a plack area around the screen. i dont know how to fix this.

if same can help me thanks

olso the icon of the app shows construct 3 icon not the one i uplode

you better learn more about construct 3 and read at least the basics of the manual before publishing your apps

about the icons, you have to change them on the project tab, there's 6 icon sizes and 1 loading logo you can customize

for the screen to adjust to the window size, you need to choose in the project Properties the Full Screen Mode. Try SCALE INNER and see if it works for you.
