Hi,

At a recent event I wanted to use vMix Call on my iPhone 6s as a Program Out monitor at my camera position. I set up a Call with a 720p 800KB return video to my phone, and it worked great with less than 1 sec latency.
But during the first break I disconnected the call to use my phone, and when I went to reconnect, the return video on my phone would freeze and only update a frame every 5 seconds or something like that.

We where streaming and recording continuously all day, so I couldn't do much troubleshooting in vMix.

I tried reconnecting on the phone on both wifi and 4G, and did a full restart of the phone, so I'm quite sure the problem wasn't there.

Has anyone else had this problem, and any tips on how to avoid it?

Thanks!
