Hello,
I will look over this tomorrow and fix the issue.
EDIT: I did some tests, and the repinning (with changing link) works with no issue. I tried with an old website of mine, and it failed because (although PB thought it worked) the website was considered spam. I tried with a new link, and it worked. Please try to manually repin with your link and see if it works, maybe your link was reported? Also, can you please tell me your support ticket ID, I can't seem to find it, we can talk more there.
Thanks,
Vlad
