I bought new vivosmart 4 in Japan week ago , but there is no Pulse Ox icon and data in VivoSmart. Anyone has this problem? and how can I solve it? Please advise... Thanks a lot...
Do you have a snug fit on your device?. The Vivo will record most things fine with a looser fit. But it needs to be snug for Pulse Ox. If this doesn't help, you can contact Customer Service. They do an excellent job of troubleshooting and explaining.
