Used to love Duolingo but don't expect to keep your progress if you get a new phone! I even paid for the Plus service and made sure to log into the correct account, but after getting a new phone all my progress was lost. Their support forums didn't have an answer and it is almost impossible to open a support ticket. Seems like the only way to contact support is with a bug report so I did that. If I get a satisfactory response I'll update this review.
