So I got my shield tv loaded up, system updated to 1.3 I believe, connected my accounts to Netflix and hulu plus. Cool, I'm ready to side load some apps. So i go into the Google play store to get es file Explorer. Um, wat? It just sits there spinning the loading cursor with nothing else happening. Can't find much from searching on Google other than some 2 year old posts about it. I cleared cache and data and forced stopped it just in case. No dice. Restarted the shield tv and still nothing.
Halp?
Edit: fixed it. Apparently you can't enable unknown services before accepting TOS?
Make sure you have all system updates installed. Then see if it works.
