Exactly the same problems, battery drains in 3 hours, wifi and LAN connections unstable. I need to know when will the update with the fix be released, if not I would have to go back to Catalina. Not ok Apple.

Hi. I have two MacBook Air computers, one old and a brand new one. I experienced the same problem in the old one, and the new one was working fine. I had installed Zoom 5.0.4 in the old one and Zoom 5.2.4 in the new one. In the old one I uninstalled the previous version and installed the new one (5.3.4) and it worked fine. So, I guess Zoom fixed the problem, as long as you have Zoom 5.2.4 or newer, it should work.
