Drupal 7, CiviCRM 5.39.1

When I edit an activity with a few contacts, I am given the opportunity to edit those contacts. Once the threshold of somewhere between 50-60 contacts is crossed, however, there is no longer the opportunity to edit the contacts on an activity.

What is driving the difference in behavior of the UI?

50 is maximum number of Target contact that can be edited from UI.

But i think it can be changed by sending a small PR to core or implementing hook to make the field editable.

  • I support for creating a setting in Civi so that it can be altered from UI or api or $civicrm_settings variable Dec 29, 2021 at 21:35
