There appears to be a bug with Garmin Connect Mobile on iOS since around mid-June this year in regards to sending (at least) Index Smart Scale synced Body Fat % to Apple Health as BMI :o
There's a thread over on the Index Smart Scale forum section, but in reality, this is the fault of Connect Mobile, not the scale.. so I'm starting a thread over here.
To summarise
• Garmin Connect has not been sending Body Fat % to Apple Health for several months.
• When you dig into the "Show All Data" for BMI I see two data points for every day, one that matches the recorded BMI, one that correlates to Body Fat % (rounded to two decimal places)
