UPDATE #1: We’ve addressed this issue in our Titans Grove Expansion update:
Some Zwifters are reporting game crashes on certain iOS devices (iPhone 6, iPod Touch, iPad Air, iPad Mini 2) after the desert expansion update. The crashes only occur when riding, running, or just watching in the world of Watopia, and all other worlds (New York, London, Innsbruck, and Richmond) should be functional.
If you are experiencing the Watopia crash on any other devices, please open a support inquiry detailing your device, game version, and what world you are crashing in.
If the option is available for you, please use any other compatible devices to ride or run in Watopia. While there is no timeline for the fix as of yet, our dev team is aware and actively looking into this.
I’ll update this post as we receive new information. Thank you for your patience!
