1. Added the assets

2. created appx folder in the build directory, keep the package.json as mentioned above.

3)Make sure the app logos named should be specific as metioned in the link .PNG format.

4)Earlier I had icon names as e.g: Square44x44Logo.png format .PNG then after changing the name to Square44x44Logo kept format .PNG as it is I was able to solve installed app issue.

What i realized by this is naming convention does matter a lot in case of applying icons. So the main issue caused due to pont 4.

Wow this one is really nice, & color combination is extra ordinary, good job man. Keep it up.

Though its nice explanation, but I didn’t worked for me. I cant understand how do I solve it.

You can use Facebook Messenger to lower image size, or you can use paint it tool in windows OS, canva also works good. If you know how to use PS / photoshop then other things you don’t need to use.
