Auto-accept invite disable

Hi. I have switched off auto_accept invite feature in my application, but it still works, how is possible to disable it?
Steps that I have done:

  1. Make a PUT request to https://api-{appid}.sendbird.com/v3/applications/default_channel_invitation_preference to switch auto_accept field to false
  2. Checked that this field is disabled by GET https://api-{appid}.sendbird.com/v3/applications/default_channel_invitation_preference.
  3. Send an invite to my user
  4. User automaticaly joins group
