Joann is looking for an app for Zoom. She's heard that Zoom is barred from the Apple app store for macOS Big Sur. Is this true? Leo says that Apple has really beefed up security on the Mac with Big Sur, and the real issue is that you need to upgrade to the latest zoom version. Go to the Zoom website. That's where you have to get it. Not the app store. Download and install the latest version.
You can also press the CMD key and space, then type ZOOM. You can then open the Zoom app, and then you can update the app under preferences.
