I just passed 3k steps (in one hour of constant movement) for the day in normal 24/7 mode with the watch reading my HR over 80 bpm (and as high was 97bpm) the whole time. I only have 91 active calories and nearly 1200 resting. It seems nothing I do can legitimately get the watch to count calories as active. Wasn't like this before 2.80. Already done hard resets; nothing is fixing it.
Already reported to the team. Yet again, with an update, Garmin borked Calorie counts.
