You need to move at least 200 Meters.

[imrvshah]

ahh, Interesting.
I will try one more time with more distance.

[christocracy]

This aspect of the iOS plugin is highly reliable.

Just keep moving.

[imrvshah]

Sounds good!
One more thing, Once the iOS reboot the app, it starts to get notifications, even if the app is killed. Am I correct?
I was checking this video https://www.youtube.com/watch?v=rFNDIQLEouo&feature=youtu.be&t=70

When your iOS device reboots, your app doesn’t boot until a significant location change occurs. When the location change occurs, iOS will launch your app in the background, just as if user launched from home screen, to service that event.

I did get the pings.
But I know the issue now what's wrong.

I am facing this issue in only iOS devices iOS 11.1.2 with iPhoneX , iPhone5s iOS 10.3.3.

it stops sending GPS pings and application is hanging on the splash screen. I guess the issue is the app is not rebooting but not sure

This is working fine on Android devices.

Me too! I'm wiping my 6s to test alongside. Must be a Cordova issue related to app booting in background and periodically hanging on splash-screen. I'm seeing a lot of crashes too (unrelated to plugin).

I have no such issues with the React Native version (uses exact same TSLocationManager.framework as Cordova version.

I'm seeing some success on iPhone X after removing cordova-plugin-splashscreen.

I'm seeing Background Fetch notifications now. Wasn't seeing those before.

Just got another white-screen. Captured this in JS Console:

[christocracy]

Still, I'm seeing much more stable behaviour now without cordova-plugin-splashscreen

[imrvshah]

I have given a try with removing cordova-splash-screen plugin but it did not work for me.

There's something really strange going on with iPhone X apps in background. they refuse to suspend. You definitely want that fork of cordova-plugin-ionic-webview

cordova plugin remove cordova-plugin-ionic-webview
cordova plugin add https://github.com/ghenry22/cordova-plugin-ionic-webview#integratedFixes

I tried this solution over the weekend. It seems like the same issue on iPhoneX iOS 11.2. In the killed state it is hanging on the splash screen.
I am confirming that it still exists in iPhoneX and unfortunately I don't have any other device as of now to test on.

[christocracy]

Yes, for me my iPhone X is still hanging sometimes.
