Thanks for you replies. Unfortunately, no new insight from your reports.
I can only repeat what I think the new conditions are:
- Start the game for CDP bonus after midnight GMT (=UTC).
- Play solo strokeplay, maybe MPs like blitz, but not A/S (unless you invite to the game).
- One shot is enough to get the CDP count and bonus.
I chose strokeplay, then click PLAY (accepting the default of ranked game and random course), use a free CC pass, take a tee shot and decide whether to continue or to quit it.
Selecting a one hole practice game would bring easy 40+ XPs more if I finish the hole, but why waste so many clicks and ball life - I don't need XPs.
