On Sunday, May 07, 2023, Zoom deprecated the current SDK version that we were using to run live classes in a secure manner. Due to this, the live classes on the Android app have stopped working. 

We have fixed the issue and the new app version has been released. You can update the app from the app builder or you can reach out to us at care@graphy.com. We will help you update the app. 

As an alternative, you can ask your learners to join the live classes from the website.
