After reporting that Body Battery readings on more than one compatible devices does not get taken into account, I realised that something else is totally not working.
I did 23,000+ steps after a run and a walk with my MARQ but the steps goal remained the same at 8450. This problem started once I bought a Vivosmart 4, which my phone would sync with when I get home. Something in the way this data gets reported or the way in which true up works results in Garmin Connect not updating my daily steps goal.
Pretty annoying, I am already asking myself why I even bought the Vivosmart 4 when I have known Garmin's execution in syncing data on multiple devices to be spotty at best...
