"Negatives" Topic won't Unlock
I've finished "Dative Pronouns", "Numbers" and now "Household", but Duolingo won't let me progress. The Main Study Map indicates I've only got 35/144 for Household, but I've finished all the exercises and actually have 69 so far, as confirmed when I go into the module. This should be enough to enable progress (50 is the minimum).
I've logged out and back in a couple of times, and that hasn't sorted it out, so I'm a bit stuck at the moment.
Any ideas? (I thought I'd posted this earlier, but it doesn't seem to have appeared - apologies if it appears twice)
