Same here.
I already created a ticket. Hopefully i receive a prompt response there. But even that is confusing because I didn't receive a confirmation email that a ticket was created, and I also don't know where I can check the status of my ticket.
All in all, this is not a good start, and I will test other systems like TrueNAS. With open-source software, at least I know that I might need to tinker, but with paid software, I expect a better workflow. Moreover, I'm not sure about the reliability of Unraid if even basic things like registration completely fail. With a NAS, reliability is naturally important to me.
