My account is also locked. Maybe this happened because nonkosher in from a new location from a new device.
I talked to support and they asked me a set of question which I have answered and now support has asked me to wait as they have forwarded the issue to the administrators to unlock my account.
Been a few days but nothing has been done.
That means if you try to open from a different location your account will be locked?
Did you enable 2fa in your account?
If you enable then they shouldn't lock it because your account is already secured with 2fa feature mostly hackers can't access it unless you have forgotten your password and tried few times to log in.
