FB share not working on some iOS devices

[ghost]

Hi just a problem with iOS,

tried to use the plugin to share something from our app. I used iphone 6+ with 10.3.2 ios version and the share to fb function works. however when i ran the same app, on an iphone 5s or 6, everytime i share something, it prompts to the "login with fb dialog" instead of automatically sharing it to facebook (which should return a "facebook posting success" message upon success). On the console it just says user cancelled (which I believe comes from the plugin). Any ideas?

plugin : cordova-plugin-facebook4 1.7.4 "Facebook Connect"
ios version on both devices : 10.3.2
fb app version: 100.0
ionic v: 3.5.0

here is the method :
`function post_to_facebook(data) {
$log.log('Posting to facebook', data);

	// Check user fbplugin login status 
	facebookConnectPlugin.getLoginStatus(
	function(response){
		if(response.status == 'connected') {
			// post to facebook
			var facebookString = "/me/photos?method=post&url=" + data.twitter_picture + "&caption=" + encodeURIComponent(data.desc) + "&access_token="+response.authResponse.accessToken;
			$cordovaFacebook.api(facebookString, ["publish_actions"])
			.then(function (result) {
				console.log(result);
				loading('hide');
				toast("facebook posting success");
			},
			function (error) {
				console.log(error);
				loading('hide');
				toast("facebook posting failed");
			})
		}
		else {
			loading('hide');
			toast("facebook posting failed");
			return;
		}
	},
	function(response){
		loading('hide');
		toast("can not post to facebook");
		console.log(response);
		return;
	});
}`
