I’ve been playing around with AppInventor with 3 of my students. They have their own laptops and borrow an android tablet. They all connect to the same school’s wifi (where some features seem to be blocked) and the same as the tablet. For one girl, after scanning the QR it works in the tablet (and in my personal phone), while two other kids scan the QR, try to connect and NOTHING HAPPENS! I’ve tried nearly all combinations: let them use another computer, log from a different gmail account, reviewed that the girl properly disconnects before passing the tablet to them, tried to connect with my phone… I’m running out of ideas and cannot guess why it is working for her and not for them 🙁
