**Description**  
I happen not render view sometimes.  
I checked myUserId is not zero and `addAttendeeVideoUnit` return result is true.  
How to resolved not render view sometimes?

```auto
AndroidView(
        factory = ::MobileRTCVideoView,
        update = {
            val videoViewManager = it.videoViewManager
            val renderInfo1 = MobileRTCVideoUnitRenderInfo(0, 0, 100, 100)
            renderInfo1.aspect_mode = MobileRTCVideoUnitAspectMode.VIDEO_ASPECT_PAN_AND_SCAN
            videoViewManager.addAttendeeVideoUnit(
                myUserId,
                renderInfo1
            )
        },
        ...

```

Hi @max555, thanks for the post.

Can you confirm whether or not you are seeing the [`onSubscribeUserFail`](https://marketplacefront.zoom.us/sdk/meeting/android/us/zoom/sdk/ICustomizedVideoSink.html#onSubscribeUserFail-int-int-long-) callback when this issue is present?

Thanks!
