Zoom Whiteboard keeps freezing on multiple devices

[eesenwa]

The zoom whiteboard feature freezes while drawing repeatedly every minute or so. This occurs on two separate devices and happens due to the Zoom whiteboards feature freezing. I am on Zoom version 6.4.1. I am an educator who teaches remotely so I would appreciate a solution. 

it can be unfrozen by minimizing the app but this workaround is not feasible to do constantly.
