I created a group for the Member Advocacy subcommittee of CCPA and sent out invitations to the group members, Some of the members joined the group, but some did not, so I wanted to present the invitations. The last time I tried (a few weeks ago), I was not able to -- I got an "unexpected error". The only way I could resent the invitation was to delete the original invitation and create a new invitation -- which I did. When I tried today to resent invitations, I again got an "unexpected error" if I tried to resent send them all at once or a message saying the invitation could not be sent if I tried to resent them one by one. Is there a problem in the system?
