Not necessarily a bad thing. This latest build is nothing to write home about, but...... Have you checked and confirmed that you have your update settings on "FAST", as this was a fast ring update only.
The only other thing I noticed is the note that says..... "It may take up to a day to detect new updates after settings changes." So if perhaps you've recently adjusted from Slow Ring to Fast Ring or back and forth maybe that may have some impact on the delay in your seeing the build availability.
@Trouble you got that right . It just started to download the build today and installed it. Other updates might come for the rest of the day since its not exactly the build Ive seen it discussed on youtube.
