Firstly thank you for this topic, i have got this problem about month ago, still cannot correct this issue.

I have made everything step by step according to your topic, but at the end got such error: "One of the accounts you are trying to link has not been verified. All accounts must be fully verified before they can be linked."

P.S. My second account is fully verified: "Level 3 Verified"

Do you know how can i fix it?
