Hi Pascal Reeves,
Based on your description, this does not appear to be a Windows device issue. This strongly suggests that the issue is tied to your Microsoft account's registration within the Windows Insider Program rather than anything configured on the device itself.
A few things to verify:
- Confirm that you are signing in with the same Microsoft account that is receiving the Windows Insider emails.
- Try opening the leave-program page in a private/incognito browser session and sign in again.
- Try connecting through a different network, such as a mobile hotspot, or use a VPN to determine whether the issue is related to network routing or a regional service access problem.
- Try accessing the leave-program page from another device, such as a different computer, tablet, or smartphone, to rule out a device-specific authentication or browser issue.
If the behavior persists, please feel free to let me know.
