Reset gear of activity not working?

[Matthias Simon]

I try to reset the gear of an existing activity. The documentation says, a PUT on /activities/{id} with { "gear_id": "none" } should reset the gear.

So what I do is this:

$ curl -v -X PUT -H 'Content-Type: application/json' -H 'Authorization: Bearer <my write access token>' https://www.strava.com/api/v3/activities/1886739262 -d '{ "gear_id": "none" }'

My access token has write permissions.

Expectation:

A representation of the activity is returned, the field 'gear' is null and when I view the activity under https://www.strava.com/activities/1886739262 no gear is shown.

Result:

A representation of the activity is returned, the field 'gear' has the old gear set and when I view the activity under https://www.strava.com/activities/1886739262 I see the old gear.

Any hints?

Thank you

Matthias

I have similar issue with clear the gear. I'm uploading a route (gpx) it sets default sport type (e.g. Run), then I update the activity with changing the type as per user's selection (e.g. Bike) and reset the gear in the same.
{ "gear_id" : "none", "type": "Ride", "hide_from_home": true }

After I open the activity in Strava it is selected with the default bike from the profile.

Later (after 30s) manually updating the activity with only { "gear_id" : "none" } - it works and clears the gear.

I feel there is something related with the changing activity type requires more time and webhooks could fix my problem, but it's complicated for me to use them for now.
