Umingle Camera Feed Not Visible to Other Users

I have been using Umingle’s video and text service from Bandung, Indonesia for several months, and during this time I have experienced a recurring technical problem. The people I meet on the platform either cannot see me at all or they see a different camera feed instead of mine. This problem appears only on Umingle. I have tried using a different brand/platform and everything worked perfectly there, so I believe the issue is on Umingle’s side rather than with my device, camera or internet connection. Because of this situation, I cannot use the service properly and my user experience is seriously affected, even though I am not using any paid options. I kindly request that Umingle’s technical team thoroughly investigate this problem on my account and on their system, identify why my image is not shown correctly to other users, and provide a clear explanation and solution so that the video and text features work normally for me again.
