In the manual for the FR 630 it say´s that you can set the GC Mobile app to play motivational status messages on your smartphone during a run... so far so good.
From the pdf: "...audible warnings include lap number and lap time, pace or speed and heart rate data. During an audible warning Garmin Connect Mobile app closes the primary audio from your smartphone to play the message. Volume levels can be adjusted in Garmin Connect Mobile app"
Non of this is working in my app for iphone! The only option I have is "lap number and lap time". Moreover, the volume does´nt even go back to what it was before the audio message. It stay´s muted to minimum the rest of your run
