What do you think could have caused the rejection ?

Downloading an APK file from an unknown source is not safe. Please, do upload some screenshots instead.

@ki-themes Thank you for your quick response.
I also upload screenshorts.

Please, only share images ( no APK files )

Okay, Please any other issue in my application ?

I don’t see the images on this thread
