duolingo 'says' I have not practiced, when I have.
duolingo ... I don't know what 'clock' your software uses, but it keeps 'saying' I have not practiced, when I clearly have. I have only missed one day, about 2 or three weeks ago. I am not really sure of the date or week. But, this is very annoying. The software asks me to 'wager', but then invalidly nulls and voids my wager.
EDIT: I use my computer 24 hour clock, from 12 midnight, to 24 hours later, per each day. Except for the one time mentioned, I always practice between that time. I cannot understand how this keeps happening.
