I have been using my new Vivoactive 3 music without much trouble for about a month now but on today’s run just after the fireworks graphic appeared indicating that i had reached the daily steps threshold, my music stopped playing, and whenever I tried to start it again I received a “media error occurred” message. The device was then extremely slow and did not return to its usual tracking display. I wouldn’t otherwise mind this but I appear to have lost the activity due to this error which is quite frustrating for a new device. After a restart the watch appears to be functioning normally again but I worry that this may happen on a subsequent run.
