Good to know everything was resolved, but did you ever find out why your signing account was suspended? That's not something you brush off as haha silly Microsoft..
They should definitely put up a statement addressing it. Moreover what they plan in the future to avoid such traumatic event, this is not a “simple sign program”, this touches fundamental parts of the OS.
Apparently it's quite widespread, so I would assume a bug on their side. That's what support seemed to imply at least. We're still blocked at my company for one month+ now.
Microsoft are saying it's because those accounts didn't undergo verification for the Windows Hardware Program
