Is it just me or are you getting useless insights in the morning too?
It's totally useless if Garmin Connect tells me at 7:00 in the morning that I'm not very active on thursdays - I didn't even get up yet and Garmin Connect already judges about the current day? It's also not the case that I've been inactive the thursdays before - several activities and >100% steps on all days.
Is that a timezone problem? These insights do not make sense in any case, at least not at 7 am in the morning...you can tell me at 8 pm or so but not earlier.
