I found a problem with TV with this build.
My TV time had got out of synch.
So I got the TV back into synch.
Now YoWindow was showing expired.
So I cleared the data of the app.
Now every time I tried to add a location Network Error displayed.
I uninstalled YoWindow and reinstalled this build.
Try to add a location and Network Error displayed.
I unintalled YoWindow again and installed the last good build.
Now I am able to add locations with no error message.
I hope this is an easy fix.
