Suddenly my mouse cursor was not working on Google Docs and while i searched on Google, this thread showed up on the 1st page, so this seems to be issue only with Brave Browser
Also that thread doesn’t have a solution or clear answer and was Auto closed by system
If you’re having the same problem as this above thread, the simplest and Quickest solution is to Allow Fingerprinting and Everything will be back to Normal
Brave’s Fingerprinting block will break Google Docs cursor Functionality
