There's also difference on pc between playing game on apps.facebook page and on top11/play
From personal xp, transfer market on top11/play > apps.facebook. I went on apps and shortlisted 5* auctions ending in next 45min
Refreshed page few times, no new players. Closed apps, opened top11/play, few new 5* players with auction ending in next 45min. I don't know why, but it seems game works better on their page than on facebook.
