Have an issue with usergrid and ng-maps (googlemaps API). Need Help!

[#1]

I'm developing a website (matchbus.tours) which uses :

• Usergrid
• ng-map and googlemaps to display a map with markers
• angularJS
• angular-route

since the last update of googlemaps in april 2018 im having the issue, that the site doesn't load the ng-map anymore.

the console gives the following error:

<code>map.js:86UncaughtTypeError: g isnot a function
    at Object.ju.f (map.js:86)
    at Array.<anonymous>(js?key=APIKEY…libraries=places:86)

I don't understand the problem. I know, that removing the usergrid.js (https://github.com/apache/usergrid-javascript) include, resolves the issue but i need usergrid.

Thanks for helping me.
