Users are supposed to see this notification — once — when a new app is accessing your screen for the first time, or when it has been more than 30 days since it last accessed your screen.
If you are a frequent user of Zoom or other third-party video-conferencing apps on macOS Sequoia, you may run into an annoying but minor issue: a notification repeatedly popping up to let you know that your program has accessed your screen.
Note that even when it has worked, the video-conferencing or screen capture app you're using may notify you one more time when you first run the program again, but it should not notify you again after that.
This should also cause the repeated notifications to stop, though you may see the notification one final time when you next open the video-conferencing app.
Unfortunately, the hidden preference file that gets written to after the first notification is not correctly rewritten with a proper time stamp, causing it to reappear repeatedly.
