iPad broadcast stops when changing apps

I have TeamViewQS installed on an iPad (iOS 14.1).  I can establish a connection to it from my PC, and can start a broadcast from the iPad and see the screen on my PC.  The first app that I open after starting the broadcast works perfectly.  I can see everything that happens on my PC, for as long as the app is open.  If I click on the home button, my PC reflects the change without issue.  As soon as I open a different app, however, the broadcast instantly stops.  After a short wait, I am given the option on the iPad to start the broadcast, at which time the issue repeats.  Is there anything that I can do to ensure that the broadcast remains throughout the entire session?  I am trying to find a good way to assist an elderly family member who is not living nearby.
