We're using Jira on the Cloud.
We have one user (UserA) who, when trying to bulk change issues, does not see the text box to enter in the assignee beside the "Change Assignee" checkbox. It's just blank there.
I'm the site admin and I've logged in myself, tried to bulk change the same issues, and I see the text box to enter in the assignee beside "Change Assignee". I've logged in as another user (UserB) who has the same permissions as UserA and repeated and also see the text box without a problem.
I've even changed UserA to be a site admin, but she still is not able to see the Assignee text box.
This worked for her at one point. Something changed for her account. Any ideas?
