This problem has been periodic recently for trail runs and recovery road runs. I've not changed anything for these activity types with the way it tracks gain. Many times my watch will just fail to register any elevation gain during the activity, but it will track the gain toward the number of floors gained per day. This is increasingly frustrating.
Is there any fixes in the works for this problem? Below is a snip of the elevation graph from connect and also the elevation graph from strava. The total gain was approx 5,000ft that was ignored.
