Comment:

 Thanks for the report , however the `m2m_changed` signal was created for
 automatically created intermediate models. If you have an explicit
 `through` model, you can attached `Model` signals to it, i.e. `pre_save`,
 `post_save`, `pre_delete`, and `post_delete`. Personally, I would use add
 this logic to the
 
[https://docs.djangoproject.com/en/4.0/ref/models/instances/#django.db.models.Model.save
 Domain_Policy_m2m.save()] and don't use signals at all, this is not a
 situation where signals are needed. If have further questions, see
 TicketClosingReasons/UseSupportChannels for ways to get help.
