Windows 10 Texts On PC Messaging App

[EMINENT 1]

no, the pc app is just meant to handle skype texts - not SMS.
but skype texts and contacts where broken (for me and many others) in the last build (even after "fixing" it like MS described).
now it works again (for me)

contacts are synced over all devices - should be the same anywhere...

I don't think that is the goal. SMS was promised in the Jan. event and is all I care about since I don't use Skype. I've seen my ATT carrier texts and contacts on my Surface Pro 3 Skype messaging app. I was able to send texts from it too a couple builds ago to my 830 on W10M. It stopped displaying since the build before last on pc. I'm wondering when it'll be back and if anyone has seen this too?
