strengthening skills is becoming so stressful !
I've noticed that to strengthen any skill i have to redo it at least four or three times before it turns gold ! why is that's happening ?
If the skill had really faded out of your memory (for example, one or two strength bars left), it can take quite a few lessons to return it to its golden state, especially if you get a lot of questions wrong.
If you and Patrick.Phang are both having the same bug it indicates that it may be a glitch in Duolingo. If this might be the case and your problem isn't resolved in a few days, you can report a bug. Duolingo usually does write a non-automated response to these reports, and they often never tell you if they fix it, so don't be frustrated if you don't here a result.
Hope this helps! =)
I am glad that I am not the only person having this problem. I have found that if I come out of Duolingo and then go back in, it has sorted its self out.
Since the recent update, I have been unable to complete ALL of the strengthening skills. How many new ones are being added each day?
yesterday all my skills were at their golden state, this morning more than ten of them has to get strengthen again !!
I have only had to do 4 each time over the last couple of days. If they don't clear once you have just finished one, come out of Duolingo and then go back in. It is laborious but it works.
