I tried," Je suis en train de finir cet exercise, et je me déconnecte." Is there a reason this does not work here? thanks
I used "en train de finir" also, and I can see no reason why it shouldn't be accepted. Reported.
Jan 2022 - a year later - and it still isn't accepted. I think it fits the sense of the sentence better.
The top suggestion for "logging out" was "abattage des arbres" which will be how I imagine it from now on. Putting on my lumberjack duds, over and out!
