Hello all,
in the last few days I've seen a strange thing happening: on my TomTom Spark display I see steps are 1.068, but after syncing the steps (today) are 1.099 on the app (on android 6 Nexus 5).
This is the the first time It happens; usually the steps number are identical on both the watch and the phone app after synchronization.
Is this normal or is there something to do to make it doesn't happen any more?
