 D/QBASDK: Receive Video signal ' call', from User: 32321337, sessionId: 85173bea-bd21-45af-830c-899942e9e9df
 D/BaseClient.: Call offer message received from32321337`
This means the device receives the call, but does not display it. What is the cause of this? QuickBlox SDK version is 3.3.5. I use Q-municate as base.
