Manycam App Facebook / YouTube

Hello: I recently purchased the ManyCam Studio License.
I am using my iPhone11Pro(video and audio - ManyCam App) connected to my Macbook Pro -ManyCam Studio. And I am Live Streaming to Facebook and Youtube simultaneously.
Also Monitoring audio via my Airpods.

  1. Audio cuts in and out. I also have Audio Sync problems.Sometimes 1 sec lag and sometimes 20 secs. Why is this? Would you know what the problem could be?

  2. Sometimes after Youtube live feed has finished, the recording is drastically shorten from 20 min to 3mins. Capturing only some frames.

Can you please provide some recommendations?
This is very annoying.
