Comment:
> In a branch I am working on, I am adding a post-save signal to
OrganizationUserAssociation. What I have found is that this isn't called
when `organization.members.add(user)` is called.
Yes because `.add()` doesn't call `save()` on
`OrganizationUserAssociation` instances, this is a bulk operation. You
should use the [https://docs.djangoproject.com/en/3.1/ref/signals/#m2m-
changed m2m_changed] signal.
Closing per TicketClosingReasons/UseSupportChannels.
