WebStore Market Points Milestones may still be available (if haven’t started them yet) *only* if you had not already claimed prior week's Free Weekly Market Points. Think the reset date is still upcoming, so can double-dip and get current/ending Weekly Pts, plus then another new Weekly Pts, to make up for having missed some Daily Market Pts so far.
(*but if already claimed existing Weekly before this started last week, then you only get the new/upcoming weekly, and will have to be exactly perfect for all 7 Daily Market Pts).
Also, depends if you missed any of the earlier DailySuperEvent milestones last week (all 7 days, all 3 milestones per day).
