I have some complaints (still) about this and can't believe it isn't a relatively easy fix if someone would just care enough to do it.
1) When you add a manual activity, it is a pretty "dumb" activity. It does not pull Steps done during the activity time given, nor does it pull Heart Rate, both of which are automatically recorded and known, and there is no reason it shouldn't!
2) Also, manually-added activities don't seem to count towards intensity minutes, I assume because they don't look at the HR for the time of the activity.
This is so very basic. Why can't this be done? It seems like it is a software/app issue, as opposed to the watch itself, so an update should do it. I have searched but cannot seem to find any place to make a suggestion that might actually get some attention by the people at Garmin. Any tips or suggestions? Am I the only one who wants this? The other major companies all do this and I can't fathom why Garmin, in nearly 2021, does not.
