The "strengthen skills" is back on iOS!
Finally, it's back! Thanks for this DL.
PS: from the app, to practice by yourself is defined as "practice without the competitive edge". Seriously?! This has nothing to do with it, but nevermind the feature is back and that's what matters I guess.
Ok, the feature is back, but it's not working for me. I get the three animated dots and the "Quit" button at the top left, and that's all. I can't tap on the "Quit" button or anything. Same story if I close the application and restart it (I have already tried 3 or 4 times).
I therefore thought that I would try to delete the app and reinstall it from the App Store (incidentally, I noticed a few other apps that claim to be from DL and for which you have to pay...?!).
After having reinstalled the app, I started it and got three animated dots. Then, by some kind of a miracle, I was invited to enter my username and password, but now I am stuck. The app tells me that it can't connect to DL?! Seriously?!
EDIT: it's now working again. Could it be that there was a temporary problem between the app and the DL server, or something along those lines?
