Found the problem. They changed how they access XTRA and my ad blocker was blocking access to their new method. Had to change settings in my ad blocker to let WinIt work.
Yeah, when I get on free WiFi at some businesses, Xtra works fine, but at others, they must have some kind of network-wide ad-blocking in effect (nothing I can control from my phone) and Xtra won't load yet the other games do. So that one server used for Xtra definitely gets caught by some ad-blockers while the rest of the SYW stuff doesn't.


I guess just be glad if they're still letting you get points from playing the games, since it seems like not allowing you activate Sweeps Weekly offers would go hand-in-hand with getting blocked from Sweeps entirely.
