What might be some reasons a user of a project can no longer tag or @ anyone in the comment box of a ticket they own? It seems to be isolated to this user. We have tried in Edge and Chrome with the same results. Cleared cache.
This user was recently added to another project as a customer and since then, her ability to tag has been lost.
I have tried to migrate to Atlassian (she is a standard, trusted user of Confluence, JSM, and Jira Software). I saw an article that mentions the users profile settings but not finding anything that seems to be related to tagging or the ability to tag.
