I am getting this update message, only to be told file is corrupted when trying to update, then it reminds me the next day. I searched online and found a --ignore command for Terminal, but that doesn't seem to work in Big Sur? So I'm not sure how to remove this update as the application is nowhere to be found on my laptop.
