All EFL students are told that you mustn't use present perfect (have done or have been doing) in a clause with the subordinating conjunction WHEN, but sadly, you have been misinformed, as you will understand when you have watched my class on this topic. Only 8000 zaps (for 24 hours) for lifetime access to this course. I do private lessons on HiveTalk for zaps too, so send me a DM if you are interested https://blossom.primal.net/e4e505111e852e081bc6d850caaae5f776da7afa96688068a19e15631168a243.mp4
