i have this happen occasionally, but normally notice that my Vivosmart HR+ has the music control screen on and i've just knocked it inadvertently, if you go into the device settings on Garmin connect mobile, you can turn the music controls off
I really like my 2017? vivosmart HR watch and finally found the answer for turning on/off the Music Control using Garmin’s Connect app on an iPhone, in case anyone still needs it. A hint to help you remember is that the Music Control is a Display Option in the Device Settings. STEPS: 1. Tap on [More] in the bottom right of the Connect app. 2. Scroll down and tap [Garmin Devices]. 3. Then tap on [Device Settings] 4. Tap on [Display Options]. 5. Scroll down and tap on. [Music Controls]. 6. Toggle on or off as desired. On mine, ON is a blue “I” and OFF is a gray “o”. Hope this is helpful. TMH 9/28/21
