Hi Stephen, thanks for the detail explanation. We are still thoroughly confused unfortunately.
https://www.microsoft.com/en-us/itpro/windows-10/release-information shows:
Semi-Annual Channel (Targeted) as 1709 but Semi-Annual Channel as 1803 i.e. deploy latest public feature release to all users before Targeted users?!
OMS is now reporting the 391 machines we have on 1709 under 'Semi-Annual' as Not up-to date which confirms the above. Last week they were Up-to-date. Obtusely the 27 machines we have on 1709 under 'Semi-Annual (Targeted)' are reporting as up to date !
We fully understand the need to push updates in to the business via limited and then wider roll out and have adopted the MS channels pushed via WUfB and GP to do this as recommended.
Please clarify. This feels like a mistake and clearly we are not the only ones to feel this.
