Re: Install apps offline in windows phone 10
Do you mean those same apps you had in wp8.1 and gone after update but shown as "installed" in w10m store which couldn't be re-intalled? I had that too and after reset the phone it goes well.
However, if you're not native english user, after reset you'll lose those non-english input method and this is a known issue of this build which hope can be solved in the next build. Other than this this build works fine in my ATIV S (yes, this is not in the offical list but it just works anyway).
