Can't seem to unlock the next set of mots ... dunno why. I've completed everything up to that point. anyone know what's going on?
I got stuck recently because, as a newcomer, I hadn't realised that the skills tree defines prerequisites. You can't do some skills until you've done ones above and sometimes beside them. For example, you wouldn't be able to do Verbs: Infinitive if you haven't already done Family. I ended up following the star that Duolingo places on the top-right corner of the skill it recommends you do next. I'm not sure if this is the problem you're experiencing, but I mention it in case it is.
As mentioned already, I have done absolutely everything prior to this module. Every extra piece in every single module prior to until the module itself says "mastered." There is nothing left that I haven't "mastered" on the tree leading up to that module. I don't know how to be more clear. The next module simply won't unlock, even though everything is complete. I don't know what else to do. Thank you for the email to help, I looked for such an email last night but could not find it. I'll try that.
