I too am having issues logging in. When I try to log in, it tells me my account is blocked and that I need to follow emailed instructions to unblock my account, but I’ve received no such e-mail.
I am able to log in if I choose the social media login option, but then log in with username and password, without choosing any of the social media options. But when I try to log in to sdkmanager, it gives me “account_blocked_error”.
