KML Points Can't Display on Android Google Map

Question

I've written a .kml file that includes some points and lines, and when imported to Google My Maps, everything is displayed. However, when viewed in Google Map on my Android device (Select from Google Maps - More settings - Your Places - Maps), points are not displayed at all. Is there anythinig wrong with the kml file, and how can I view points on Android devices as well?

Screenshots of Google Map from both desktop and Android are posted below. KML on Google Map Desktop KML on Google Map Android

The problem is solved. By adding a style to the point, it shows correctly on the mobile app as well. Below is the modified code that adds style and screenshot. Point on Google Map Android
