I have tried everything suggested in other similar forum posts and I still cannot keep signed in. I am on an iPad Pro running Google Chrome. I have tried incognito tabs as well. My network speed is clocking in 24mbps down so I think I’m good there. I just went through about 6 exercises and it didn’t save a single thing. It is pretty frustrating.
