Stopped working properly...

This app used to work flawlessly, but ever since the latest version it doesnt work half the time anymore. I use it with friends, and sometimes it wont update their location unless I ask them to turn the app on again on their phone. If they dont turn it on, the latest update can be 45 minutes ago... Whats the point.? Completely ridiculous.
