I own a Surface Book 2 that I just picked up off of eBay and a SP 6 and can't figure out why the feature updates on the Surface Pro are showing Windows 10 version 1809 but on the Book 2 it's on 1803 and I did a bunch of downloads earlier this afternoon. Shouldn't my Book 2 also be on 1809?
Thanks to @sharpuser for my answer I am back on the Windows Insider program and it is great so all is well in my neighborhood and my question is answered.
