Hi
I am trying to unshare by api.
"https://webapi.teamviewer.com/api/v1/groups/gXXXXXXX/unshare_group"
{
    "users":
    [
        "uXXXXXXXX"
    ]
}
For some groups I get this error.
{
    "error": "internal_error",
    "error_description": "Invalid argument.",
    "error_code": 3
}
After some trial and error it looks like the problem only occur if list of users contains the userId  of the user that has created the apikey ??
