I cannot add members to organization

Hi, I am a owner of seznam organization.

There are no other members (even I am not mentioned in the Organization).

When I try to add someone to the owners group, I got 401 response status on https://hub.docker.com/v2/orgs/seznam/groups/owners/members/ and message Something went wrong. Please try again. Retry doesn’t help.

How should I add someone to the Organization?

If you remove a member from a group, they no longer receive email addressed to the group. Removing a member does not delete the user’s account mykfcexperience. Also, if you remove the group owner, the group still works. MyKFCExperience
