Hey! I would like to leave a star review (5). I did a little research before I decided to purchase the plugin (a few hours), and found that some people were having trouble with it. I was hesitant at first, but quickly realized I had no option but to try it out.
So far I've only tested the login function but it worked perfectly without having to burn myself out. I even opted to compile my app through phonegap build! All you need is to add the following code inside of your config.xml:
<plugin name="cordova-plugin-facebook4">
<params>
<param name="APP_ID" value="XXXXXX" />
<param name="APP_NAME" value="XXXXX" />
</params>
</plugin>
Where the XXXXX is your app id and app name.
Great work!
