I have updated my vivoactive4 (apac jappan) to the latest firmware with Pulse ox measurement (finally!!) as well as the connect mobile to the latest (supposed to come with pulse ox function).But the app failed to display pulse ox measurement on anywhere within the app. I switched my iPhone language setting from English to Japanese then opened app. This time pulse ox measurement displayed as it supposed to be.
I was wondering whether software bug or its original intention.
Please help me to solve this issue.
