Delay in Connecting Participants Using Zoom Video SDK in Flutter App

[farshadmajzoub]

Hello Zoom Support Team,

I am developing a mobile application using the Zoom Video SDK with Flutter for both Android and iOS platforms. The application is focused on enabling real-time audio and video calls between two users.

We are experiencing a consistent delay during session joining. It takes around 8 to 10 seconds for both users to connect, and for the audio/video streams to become active.

This delay is negatively affecting the user experience.

We would like your help in understanding the following:

1. Are there known causes or limitations in the Zoom SDK that might result in this delay?

2. Are there recommended optimizations for improving performance on mobile, especially in Flutter integration?

3. Could the issue be related to token generation, SDK initialization, or event listener timing?

We would appreciate any guidance or solutions that can help reduce the session join latency.

Thank you for your support.
