Since ATT Uverse updated to new firmware on Set Top Box(STB) (IPH8110) double pushes of the same number no longer work.
Ex: I select 1002, displays goes to 102. 1104 display goes to 104.
The remote to the STB works fine in home, just the Sling-player remote is impacted.
I have tried the Grey, Black and misc others they all exhibit the same result.
