App icon not showing after downloading app from App Store

Not showing on which iOS on what devices?

Is the app itself missing, or can you see the app name but there's no image (or a placeholder image) above it? Have you see this behavior on multiple iPhones/iPads with different users (i.e. Apple IDs)?

I've seen odd behavior with app installation when the app is downloaded outside of the region its availability is set up for. Also, the restriction settings seem to cause this for some users.

I can confirm 4lio on iPhone 6s ios 11.2 app icon does not show up, check your Assets.xcassets and make sure you have all the nessesary app icons.

thats so wierd when downloading the app the icon shows but when it finishes the icon dissapears.

spotlight icon none, settings icon none.

I have put all icons and moreover Apple checks if there is any missing icon then only it allows to upload to iTunesConnect

yeah that's bizarre, i don't know what to tell you.

Thanks! I appreciate for your time.
