Thanks, Kate! I think there’s clearly something going on with the transition from the old version of the app to the new … just haven’t nailed down where the mischief is. But glad to hear that things are working now.
So … I think what I’d suggest if people have troubles with the new version of the app. First, try quitting the app and re-starting (here’s a quick ref on how to do that, since it’s different in different versions of iOS: https://www.lifewire.com/quit-apps-on-iphone-2000287). If that doesn’t help, then try manually downloading a lesson as described earlier on this thread.
If none of those work, then just give a shout here, of course!
