My wife goes out for pre-dawn runs and uses Livetrack for safety. Frequently, her location icon just turns into a "spinner," and there is a popup message at the bottom that says "Trying to Connect..." This happens quite often and leads me to believe the Livetrack service is unreliable. Which is the opposite of what a service like that needs to be.
The only user error I can think of is that her loop sometimes comes near our house which could cause LTE/WiFi switching, but a critical service should be able to re-establish and weather this, even if that were happening.
