Zoom Mobile App (iPhone X) - Kicks me off the meeting when I move to another iPhone app

When I'm using the zoom mobile app on my iPhone X, I call into the audio because I know that will keep me connected to the meeting when this problem I describe persists. I have a paid zoom account ($15/month). 

I'm on the zoom call, watching the content and I switch apps (to messages, to email, to search something while still on the zoom meeting on the zoom mobile app), I get kicked outta the zoom meeting. When I rotate back to the zoom meeting app, it automatically starts spinning, saying rejoining the meeting. If its a private meeting, the host has to re-admit me to the meeting.
I've already tried uninstalling the zoom app on my phone and re-installing. That didn't fix it. How else can I fix this?
