I've tried this multiple times on two different browsers (Chrome and IE), but I can never get the Invite Multiple feature to work in Team Management. I have 80 users to invite and I certainly don't want to type their email addresses manually, so I've tried using the Invite Multiple feature to upload a list. When I do so it accepts the list and then all the users are listed as "invitation pending". However, none of those users receives an email and when I go back to Team Management the invites have disappeared. Again, I've tried this multiple times, and it fails every time.
If I add a user individually, it seems to work.
Are other people having this problem? Is it a known issue?
