I install, and use the settings screen to copy over bookmarks, passwords, and everthing else I can from Safari, Chrome, and Firefox. Then I load up Gmail, and get a "cookie mismatch" error that makes it impossible to use Gmail. The only way to solve it is to delete all cookies from all time

Here's the fix we did in Muon:

Needs to be retested after brave/brave-core#3804 was merged... will try this out soon

I tested with the fix(brave/brave-core#3804).
After importing chrome's cookie, I loaded google.com and brave is logged in state w/o any error.

This is great news! Let's close this issue for now- we can always re-open if we get reports

QA/Blocked until we get a new build. Will be available in 0.71.107 and above. Label mistakenly added. This should be available in 0.71.106 and above.
