Verbs: Present 4 and Verbs: Past Perfect cannot be strengthened fully on Polish Duo lingo
i am just reporting that on the polish lesson the above mentioned lessons cannot be strengthened fully when using Duo on the computer. words that you have answered correctly still appear to be highlighted as new words when you do the individual lessons. Is there any way that this can be fixed because when I do the strengthen tests not all of the new words that I need to be learning are appearing. Cheers Adam
Did you use Strengthen Skills button next to the whole tree, or entered a specific skill and clicked Strengthen there? If you did the first thing, try the second one. If you did the second one, then write about this in the Troubleshooting forum, because there's nothing the course contributors of the Polish course can do, it's something wrong on the developers' side. The 'strengthen a specific skill' thing is the only potential solution that I have heard about.
