I can confirm lack of resume when playing movies from Q10 Pro, Android 7 and Kodi 17 from a NFS share. It doesn't matter if Q10 Pro has write access or read-only to NFS share, it never resumes the movie.
And I tried configuring Kodi to resume as a default action but it makes no difference if it's all default settings or configured in any way.
I'm 100% sure Kodi 16 was resuming so this must be a Kodi 17 bug.
