I've been using Jira since February, but haven't needed to add anyone new until now. I've added the new person to my account and also to the project. However, when I validate the CSV file before doing a bulk upload I get an error saying issues can't be created because [User 'her name' does not exist]. If I go into an existing issue, I'm able to select her name from the Assignee dropdown list.
I've checked every permission scheme, etc. but can't figure out why her issues are creating this error.
