Issue
Other users are not receiving the invitation to be added as users on your dashboard.
Probable Cause
Whatfix is configured to allow only upto 5 invites at a time. If you're trying to invite more than 5 users at once, the invitations fail to go through.
Suggested Solution
Send the invites to users in smaller numbers to ensure that each invitation goes through.
