Hi @garush, thanks for using our SDK.

Sorry to hear you’re running into a crash. I haven’t been able to reproduce this crash, so let’s try to narrow down what we’re doing differently.

  1. Are you using the default meeting UI or a custom meeting UI?
  2. Can you reproduce this crash using the SDK sample app?

Thanks!
