I have an ongoing problem with Strava displaying incorrect step counter compared with steps recorded on my Apple Watch and iPhone. I’ve been trying all sorts to fix the problem, calibrating, disconnecting/reconnecting, location services are always on etc etc.

Simple example as shown here, only 1k steps recorded on Strava but at least 1600 recorded by phone and watch according to health data. Why is that, every single walk I do is inaccurate regardless of location and if I have a friend doing exact same walk with me in terms of distance, their counter is always greater than mine.
