New Update - Zoom - ATEM Mini

Hello! Hope someone can helpt me!

I make my Education lessions with ATEM Mini Pro und Zoom als Client Software.

After the Update, I have some troubles:

1.) I need a high video quality, fast internet is availible.
Before the Update, I used the document camera for the highest quality
After update, the Share-Button with Dokument Camera hast gone.  

2.) I have 3 monitor.  1. Teleprompter   2. Main screen with working tools   3. Presentation Screen, which will be streamed.

Now i musst choose one of the the 3 screens.   I only want to share the Out-Signal from my Video Switcher ATEM Mini Pro.  

How can I bring it to work like before this awful Update.     I don t need this nick-nack, zoom offers now.

My main wish is a high quality resolution
