Google Map dont show map

So i am trying to implement this google map plugin but after implementing it doesnt show the map. I am pretty sure that I used the correct API key.

It look something like this

I searched for any solution but still I can find the exact answer.

I cant create plunker so this is the source code](

Anyone know how to solve this problem?

Below is my systems info


ionic (Ionic CLI) : 4.1.2 (C:\Users\Kevin\AppData\Roaming\npm\node_modules\i
Ionic Framework : ionic-angular 3.9.2
@ionic/app-scripts : 3.2.0


cordova (Cordova CLI) : 8.0.0
Cordova Platforms : android 7.0.0
Cordova Plugins : not available


NodeJS : v8.11.2 (C:\Program Files\nodejs\node.exe)
npm : 6.4.1
OS : Windows 8.1

Grey map means your api key problem.
You need to enable three APIs Google Maps SDK for Android , Google Maps SDK for iOS and Google Maps JavaScript API v3.

Regenerate your API keys following with this page instruction.

Still after regenerating the key i still get grey map, I assure also that android,ios , javascript map API is enabled

does the internet speed affects the loading speed for google maps? after reinstall platforms and googlemap plugin the only improvement is theres someone arrow in the upper left corner

I`ll mark this as solution reinstalling platforms and plugins of googlemap thanks
