I am trying my best to reach out to anyone within the insider "support" team. Microsoft Employee's part of the insider program. Not external like technical support or sales.
I have had multiple discussions with "normal" Microsoft support teams, they don't have the permission/recourses, required to help unfortunately.
I've had over 8 years as part of the insider program. I would love to be able to reach out with a personal enquiry.
Happy 8 year's!
