My 'other recommender' doesn't receive an invite.HELP!

So I’ve had logging in difficulties with commonapp.org before but it’s manageable.
What isn’t is that my counselor,teachers all received an invite to my recommendation section except for my ‘other recommender’.
I tried deleting and re assigning,changing the email address but nothing seems to work.
I’m sure the information I’ve provided is correct too.I don’t know what to do!
Anyone of you faced the same problem?
HELP!

ask your recommender to check his spam/junk mail folder, a firewall may be blocking those incoming emails. If that doesn’t help, maybe he could provide you with an alternative email addess.
