Depends what it’s on. If it’s just feedback on things like this topic is/was, then they almost rarely ever respond but they do see it. If it’s issues regarding the browser crashing, things not working as intended, etc then they try to respond as quickly as they can, assuming they see it.
Speaking of which, I know I see you have made another topic for Restore the Bookmarks / History / Settings shortcuts on new tab page
At this point I know it’s an intentional change in design, just like they removed the New Tab Page (NTP) portion in Settings in exchange for having Customize on the NTP itself.
Just so you know, I’ve actually shared your feedback to people at Brave, but I’m not sure if anything will be done about it.
