I have not been able to reproduce the behavior you are describing after a few attempts in various scenarios. The SDK and client are both able to pinch to zoom in, regardless of who is host and who is sharing. Can you please provide a video of the behavior you are seeing so that we may investigate?
We basically use ZOOM demo SDK setting Custom UI and mostly refer codes at ‘ON’ configuration.
It would be wonderful if you can guide us which part of code we can modify at this configuration.
Thanks for providing the video and clarifying on the custom UI part. I do not believe that the pinch to zoom behavior is supposed to work with the video view by default, which is why it only works within the default Zoom UI.
Correct. The video view in the custom UI is only meant to render video, so something like pinch to zoom would need to be implemented in your custom UI.
