I long while ago I had been begging to Garmin to add Hike as a filter in Activities tab in GC IOS. They did not do it, but added Strength Training although All Gym & Fitness had been there, too.
I made an experiment with the new filter, but it is buggy, none of my Strength Training activities is shown when I choose Strength Training, while All Gym & Fitness properly show them.
I made a check and not just my watch, but GC IOS show the type of these activities as “Strength Training”.
