Hi @Ivy_Mahajan ,

I have not yet been able to share the logs with our Amazon partner. The DVR playback issue, where the screen remains black, is intermittent—it happens sometimes and not others. I plan to send the logs once I can consistently reproduce the black screen phenomenon.

Best regards,
Jo Shinozaki
