If you are in preview program, there is various "ring" inside the program, but don't worry about it, you are not a member so this is irrilevant.

In the insider program there are quests to complete, questions to answer and feedback to give.

As these items are completed users earn XP and level up within the program.

What the levels mean - bragging rights with friends in the program as well as knowing that the user is helping to test out various new items that could go live to all Xbox users in the future.

Hi Volcannon,

Yes, you can rejoin after leaving at any point. It's possible that by joining and gaining exp so that you move up the preview rings to Delta at least so that you may get a future preview update where this issue is addressed and you can test it out for yourself
before those in the Omega ring or not in the preview program. Beta ring previews updates before Delta ring and the Alpha ring, where updates are tested first, requires an invitation to join.

Either way a solution to this will more than likely be tested in the preview program first. News regarding what is included in recent preview updates for the different ring levels can be found here:
