Whith Block All Fingerprinting enabled, Google sheets display incorrectly. (Looks like some of the columns overlap, making it unreadable.)
Workaround is to return to Block 3rd Party Fingerprinting, which is the default, I think. Load the sheet again.
Not a bug since the workaround is so trivial, but I thought it might be useful for Brave users & developers to know.
