"The boy is wearing a suit and a hat."
Translation:Drengen har jakkesæt og hat på.
A tad bit late, but I ran into the same issue and the best workaround (if you could call it that) was to open Duolingo on the phone's browser e.g. Google Chrome and switch to Desktop mode: that way, it works just like it would in a laptop/desktop. A bit annoying but I couldn't figure out a way to access the lesson's notes through the app. :(
