Experiencing the exact same issue. Playing a game, Restarting, Logging out/in, and even re-running the installer produced no results. I know I'm still receiving rewards, because my mastery track advanced after winning a game, but I can't see what quests I might have, my color challenge deck, or anything of those sorts. With as scarce as FTP resources are, this is a serious problem.
I suspect it has something to do with the line:
 The referenced script on this Behaviour (Game Object 'Payload') is missing!
found in the logs, as these are present in all of the logs of people reporting this problem, and not in other logs found via review of other bugs.
For unclear reasons, the problem seems to have resolved. Wish I could tell you why, but I don't have any advice.
For yet more unclear reasons, the problem has resumed.
I also have the same issue, have you found a fix?
