yesterday I started having this strange behavior on my Google Docs files where my cursor seemed stuck on the left side of the line, even though typing was possble (letters kept getting added to the right of the cursor as I typed). Also, cursor movement both on keyboard and mouse was invisible, and selecting any text was impossible.

This is a new bug where the latest version of Google Chrome acts weird with Adblockers on. More info on: https://piunikaweb.com/2021/04/15/google-docs-cursor-stuck-on-left-not-moving-formatting-issues/

I solved it by disabling Adblock for the Google Docs website

even more strangely, I only have this problem on my Google Workspace account’s Google Drive files, not on my personal gmail chrome session’s google docs files (personal also has Adblock enabled, and it doesn’t exclude Google Docs domains)
