Doesn’t work on iPad – HMH iRead for Schools Review

Fulton county school asked to use it but can’t get it to work. Tried troubleshooting steps but stilL no luck. It asks me to make changes to Sam url but what I see is mdm. When I entered the hyperlink it atleast moved from the 2032 error to user name screen where now it freezes after entering user name. I’m on the verge of giving since I can’t find any help. Can someone reach me on my email and please help!
