I did try that solution before and after you recommend me but still, my account is yet to be confirmed. Quite frustrated for me indeed. I will try to reach out the support when I have more time in the weekend. It can be about the cache, perhaps?
I have tried the same thing, and I can't seem to verify my email address after getting the link in the inbox. I click on the link, and it redirects to the homepage to show as though the account has been verified. On clicking withdrawal page, the email verification promoted still remains there and has not cleared.
Maybe Winna team need to work on this.
