I would also like to disable the useless morning report. There is literally no information on it that I need to know first thing in the morning but I do have to dismiss it every day before my watch becomes usable.
But I found a hack. If I disable sleep tracking then I do not get a morning report.
Pro: you also have a slightly better battery life.
Con: for reasons beyond my comprehension, disabling sleep tracking also disables hrv.
With sleep tracking disabled you do not miss anything. It’s not very accurate. Better is to ask yourself in the morning, do I feel refreshed or still tired. If tired, do something about it!
Loosing hrv might be slightly more disappointing. Hrv might actually tell you something useful (although science isn’t that sure, they only studied effect on ill people, not on healthy ones) and hrv measuring on a wristwatch might be not that accurate (at least, on garmins they investigated it was not and I don’t see why other brands would be so much better)
