AlaskanDame: After the update, my club's custom courses did not show up for two days in the "create a tournament" page listing of available courses . . . . then they were visible for 2 days. Now they are gone again.
For whatever it's worth, mine were on and off for the first couple of days as I reported earlier. The courses were available on Friday (which is when I created my custom course event) and they are still available today. I create events with a custom course every 4 days. We'll see what happens on Tuesday. :-\
