1. If you get a message that "this app isn't verified", click on the "advanced" link in the bottom left to move on. Video has details.
2. If you are trying to login to Drive for the first time, it may happen that the login flashed at you, then asks you to try again. In this case, When you click on the assignment, you have to click on the drive that's below it and then below that and to the right it says choose a different account. You have to click on that and then choose their google account that comes up. It has mainly been happening with new students that we have gotten this year and we couldn't figure out why it was just flashing off. It was because we had to choose the other account.
