All fixed now!
My account is blocked as well. Allthough i did find a workaround by going directly to https://support.mendix.com/ However the link to the partner portal itself does not seem to work.
Nope, not fixed. email@example.com also cannot log in since 28/4
I keep getting bumped back to the page where I choose betwen "already a partner/login" and "not yet a partner/register" (https://partnerportal.mendix.com/index3.html#someID)
