New user now hub offline

Hi there. I tried to add a new user to my account yesterday and had them create an email address. I forgot the exact steps for setup so I accidentally had them enter the welcome code. This is when the fun began. This kicked me off my app and gave the other user control. I tried to reverse this without success. I am now stuck with the new user not having control as well as mine. My hub is saying its off line at this time. When i try to add a new location it tells me the validation code is invalid and to contact support. I sent an email but was wondering if anyone on here knew what to do.

I think you’re gonna need support to fix this from their end.
