i got 2 thing to say about this build:
1- im seeing loading... resuming... alot more. specially on silverlight apps, for example the new telegram preview app. (of course i compare it to the last RS1 build i got on Production ring)
2- this is weird, vpn is still broken. im not an expert but i heard they call it dns leaking. on wifi, only some of apps send traffic over vpn, and some never does (for example facebook app never sends data over vpn). on cellular, NO app sends traffic over VPN, actually you connect it, it successfully connects but no redirection happens. traffic completely ignores vpn and send and receives bare data from provider. it is there for almost as long as windows 10 is out. (Days of threshold 1) and no body mentions it or acknowledges it. sometimes i think its criminal or something to mention this obvious problem.
