We published few help articles on all the requirements and troubleshooting in regards to the new classroom application here: https://tanzeel.freshdesk.com/support/solutions/folders/44001214382

We recommend that you try the solutions listed in the above link before trying the next step.

In case you couldn't resolve the issues you were facing, you can take the class using Zoom (like before) for the time being. We will not be using Zoom once all students are migrated over.

You can always create a support ticket and let us know if the issues you are facing isn't adequately addressed or is a new issue. We'd be happy to help.
