Why does Google Classroom suck so much? Is it the most glitchy website you've ever visited?

I can't believe this is what I'm stuck with for the rest of the school year. I've been teaching for 8 years and this is the worst thing I've ever used. It glitches non-stop. I can't make assignments, I get kicked out mid-email, Google drive won't work, the grade book doesn't work right... I swear to god, Google Classroom was made for a first grader. A normal teacher can't use it on a daily basis. I've been on the phone with Google the last few days trying to get this fixed and nothing has worked. I'm seriously talking about suing them.<br><br>Edit: Sorry I didn't make this clear, but I use a Mac and my school uses iPads. I'm at home right now on my Mac trying to do my job. I can't go into school because they are locked down.
