Alpha Insider Problem - Insider for 2 years and 10 months

Seems you have to be invited to join the Alpha ring

The current Xbox One Update Preview rings are:

• Alpha – Open on an “invite only” basis and receives updates at the earliest point in the preview window.
• Beta – Open to Xbox Insiders with a Program tenure of 3 or more months and an Xbox Insider XP Level of 5 or higher. This ring receives updates shortly after Alpha.
• Delta – Open to any Xbox Insider with a tenure of 1 or more months that has reached Xbox Insider Level 2 or higher. Depending on certain edge cases where further attention is required from Alpha or Beta rings, Delta Insiders may receive
  system updates before Beta, though this is not a common scenario. Additionally, while early system updates are not guaranteed across the Delta ring, all Delta Insiders will receive the update prior to GA.
• Omega – Open to anyone and receives system updates shortly before the GA (General Availability) release.

Most of the Alpha insiders i know of has been doing it for 4 years or more.

HI, I'm also getting that issue, however you shouldn't need to reset the Xbox, all I do is with the Xbox powered on press and hold the power button for about 10 seconds, let the Xbox shut off, pull the power cord out of the Xbox for around 30 seconds, reconnect
the power cord and power the Xbox on again using the power button on the Xbox. Seems to work for me at least.

I'm an Insider by more than 4 years now and I get my invitation for Alpha skip ahead ring less than 2 years ago, you need time and patience, do your work

You have to be in the alpha ring of the insider program or use the beta xbox app on a windows 10 pc.
