Alpha Ring, constant sign outs, failure to capture screen shot when reporting

Been having random crashes on MK11 and the in-game sign-in keeps disconnecting when relaunching the game. Attribute it to being on the Alpha build ring, but I try to report whatever ones I can when I'm not just trying to play a game.

as StuartATrueRed states, it is all down to accurate reports. The more you file bug reports, the greater the chance that when they need to top up the Alpha rings, you will get an invite.

if you do get an invite to Alpha or Alpha Skip Ahead, be prepared for lots of bugs and issues.

To be a alpha member you need to provide quality reports and they might invite you but at this stage they are not inviting new alpha members as the alpha ring is full but usually every 6 months they invite new members to alpha so the best way is to wait
and submit reports

As denis97g stated the Alpha ring is invite only. When they need more Alphas, then they will send more invites. Just keep reporting any issues you find, and continue with the activites like filling in questionnaires, quests and polls.

I am insider. Based on your activities you can be invited in alpha or alpha preview ring. Only by someone from the staff. Ambassadors can't do that. Keep your surveys, ideas and reports clear and smart. Eventually, you will get an invitation. But beware.
To be an alpha means constant updates and bugs. I am using my second xbox for that. In some cases people had to send box to repair. Alphas are the first line of deffence against bugs. For safer community. As others have said you can become beta on your own
based on time and xp you have earned.
