Problems with Zoom on iPad after latest update

After successfully taking a painting class on Zoom for months, the latest update made it impossible for the class instructor to successfully switch between sharing her speaker screen and participant screens. Once the participant screen was shared she lost the ability to go back to the instructor screen. The screen “was stuck” on the participant. This was only a problem on those for those class participants on iPads. A video of the class after the fact from the teacher showed screen sharing working properly from desktop participants. iPad participants had to log off of Zoom and log back in to view the instructor’s shared screen.
