"Strengthen Skills" always gives me same lesson
Most of my Spanish tree is gold, with about 8 or 10 lessons needing review to get back to gold. BUT no matter how many times I practice using "Strengthen Skills," I always get the same lesson (using "ir future," which already happens to be gold). Can this be fixed??? Up until now, Duo always gave me a lesson that needed to be reviewed.
If you used the "General strengthen button" then try the "Skill strengthening button"
or try my favourite method
This is suddenly happening to me with Esperanto's "Expressions" lesson. I thought it was bizarre because there were about 7 skills higher in the tree that needed practice, and normally the topmost non-gold skill is what gets strengthened. Now nothing is getting strengthened, it's just the same sentences over and over unless I strengthen in a specific skill.
It happens on both web and iOS. Here's another thread about the same thing: https://www.duolingo.com/comment/26004137
