I've been seeing and hearing from other colleagues about message appearing in an individual's Slack view from Jira Cloud app. For example...
- User A and User B both have access to our company's instance of Slack and Jira (all the same projects)
- User A posts a link in a common, unlocked (not private) Slack channel, of which User B is a member
- User B sees an alert message (which is only visible to User
from Jira Cloud App which appears below the Jira link that User B posted. The alert says: "[@User B], sign up for an Atlasssian account to view this link and join [UserA]"
- There is an option to Sign Up or a single select button defaulted to the Dismiss option.

But again, User B already has access to Jira and the related project for the linked issue.
Does anyone know why this would be happening and how to fix it?
Thanks
