Hello Windows Insiders!
We have seen several reports of Windows Insiders in the Mobile Fast ring on build 14342.1004 mentioning that their ring-selection drop-down shows "Disabled" in the Settings menu.
Settings > Update & Security > Windows Insider Program
We are aware of this issue and are actively addressing it. This is a service-side change that will be necessary and no action is required on your part.
Important Notes:
- We will not release any flights until this is corrected.
- A fix is expected within the next few days, so no new builds over the weekend. This isn't surprising, right? I can count on zero fingers how many Saturday or Sunday builds we've released to Insiders. And... we have Monday off as well. :)
- No action should be required on your part.
- We will make the necessary changes and when complete, affected users should be back on their original ring (WIP Fast)
- This only affects users on Mobile build 14342.1004 (which was released only to WIP Fast)
We will provide additional updates when the changes are completed, so hold tight! :)
Thank you as always,
Jason
