This app constantly signs me out. It's annoying to log in so frequently. And then if you need a verification code it takes awhile to get to your email and times out in 30 minutes, so if you get distracted you have to start all over! Overall it used to work better when we used it a couple years ago. Went downhill. Easier to just communicate directly with their teachers. UPDATE: I have unsubscribed from all emails multiple times, I still keep getting junk from them. DON'T TRUST WITH YOUR INFO
