I added a user to our list of JIRA software (cloud) users and added the user to a group dedicated to a specific project. He is also the lead of this project. He can see the project(s) I created under the Projects tab in his JIRA account. Yet, upon clicking on it, the project seems to try opening, but hangs with the "loading" icon displaying continuously. I can access he project without any problems from my own account. I've tried addind this user the "administrators" group as well. Yet, the same issue persists.
Could anyone help me solve this issue? I am of course willing to share more information to get the problem sorted out.
