i cannot add my registry link! Help plz!

Hi everyone! I just started my registry with Target and am trying to add it to my profile and make it visible on my WW website. However, every time I copy paste OR type in the address WW tells me it is invalid so I cannot import it. (It's a good link. I can click on it and be brought to my registry. It's the link that Target gave me.) Has anyone had this issue before. I sent an email to support, but I don't know when I'll hear back. Any help would be much appreciated! TIA!
