    Needs to go back to older version. This version is horrible. I would rather have old graphics and working app then new graphics and nothing.

    Had my WiFi relay for a month or more and cannot get the app to operate it. Despite downloading the app with latest bug fixes, the app displays a whole heap of average reading time data and input information which eventually freezes the app. Great app but needs some work to make it work consistently.
