Can't connect to Pinterest's Linked Business Account

No, what i resorted to is unlinkin my pesonal from business pinterest accounts. 

I am having exactly the same issue. My business account was linked to my personal account and now its vanished. Even if I sign out of my personal account and sign try to sign into the business account i get caught in a loop whereby it keeps asking me to open an account. Strangely if I search for my business account by name the profile comes up but can no longer access it. Did you get this sorted out. Its driving me nuts.
