Whenever I do a "strengthen lesson" on the iPad mini app, it doesn't strengthen the skill.
The problem is that I DO do individual lessons, but it doesn't strengthen the skills anyway. It feels like a bug because it doesn't strengthen on the app, but it still works on the chromebook that I use. It's kind of annoying because when I'm on the treadmill, I can't strengthen my lessons because the strengthen doesn't work on the one device that fits on the treadmill, which is my ipad.
Ya this just started happening to me tonight, I did the "Demonstratives-2" skill 6 times 20 out of 20 timed and un-timed and it is still stuck at 4/5 when normally it just takes one round(or less) to bump it back up to 5/5. Other ones are strengthening fine. (These were on a desktop, then tried once from mobile and it worked... maybe because my desktop has mic disabled and the app doesn't?)
