I recently started using Brave beta snap version on Solus Linux, here are some feedback on this beta (with shield) enable:
Half of the sites visited are displayed with a horrible font and a little smaller than with other browsers. This makes reading difficult sometimes.
The show/hide menu bar option in the preferences is not taken into account when restarting
Some popup can’t be closed on some sites.
Delete cookies on quit doesn’t work also.
