We're having a technical issue about showing up the sample sentences. Our techincal team is working on fixing the issue. I'll update here when you'll be able to check them properly.
We're sorry for the inconvenience that you have.
I'm having another problem with the flashcards. Today, while trying to select a deck to study, it just goes to a 'loading' screen and never moves past that. I tried it with several decks on Chrome and Safari with the same result. This also happens when trying to create a new deck using lesson vocabulary in the 'Deck Manager' screen.
When you're importing flashcards from our Core Word List, currently, it doesn't load the flashcards correctly. Our technical team is fixing the issue, so we'll leave a comment here when they are working fine again.
