Intune feature update policies - troubleshooting

1. Be sure that device is targeted by only one Feature update policy. If it is targeted by more then there will be conflict. So if e.g. pilot policy is targeted to IT devices please be sure that the same IT devices group is excluded from all the rest feature update policies. 

2. Take a look at MS Entra – devices – and look if for specific device there are no stale records. 

3. Be sure that telemetry is enabled on device. 

4. Try to start service: wlidsvc - Microsoft Account Sign-in Assistant
