I am doing the Maruri Island challenge. So far two stages have crashed on me about 80% into the ride. I am on an iPad with the latest software. After the crash it lets me log back on and continue the ride but at a lower level. I also don’t get credit for the ride but it does save as a Makuri Island ride. Looks like my xps weren’t updated correctly though.
My internet speed is 1.5Gigs and about 600K at the workout station.
