Does the earning ARP from watching Twitch even work? I've watched several streams for hours but never received any points. Is there a trick to this? Or is it broken for most?

Does everyone else have problems syncing their Steam library? I after i click the Sync button, about 30 seconds go by and I get the "Sorry, you can only refresh your game library once per hour." message. My Steam settings are all set to Public so not sure what the issue is? Update: It finally stopped giving me the error, but it didn't sync all the games in my library.
