During the past two days my PLTW class has experienced connection issues with Mitappinventor when the students are trying to connect with qr scanner--all of my 7th period students cannot connect, is this an anomaly--something being worked on at MIT during this time. 1:35-2:25---Please help--all of my other classes have had NO issues, including my 6th period class that meets from 12:40-1:30 pm.
Please HELP!!!
