I've recently created a Sandbox on a premium JSM environment.
Afterwards I did a "copy production data" action and all the information was copied over nicely.
However I'm a bit confused about the users.
They are already added to the Groups they were in but their status says:

Now the question is, do I manually need to re-invite all the users (resend invite) or if they have the url, will they just be able to log on?
