duolingo coming for you when you lose your streak
I left you four messages should not be an option in the answer bank. I sent you an email. I left you a message. відправив may mean sent, but the english could be either. Left should be removed from the answer bank.
Vidpraviv instead od vidpravyv-can't it be typo instead of mistake?
"I sent four messages to you" is an exact equivalent in English!
