Close browser = lose all logins

ive had this problem for about a week if not longer, when i restart my pc i lose all logins on every site, i haven’t changed anything settings wise.

sometimes its fine and remembers them, other times not.

this is not the saved password feature, i only use that for some sites but others i choose no. that feature works fine and i can login easily.

i have checked my google settings, its only me signed in and have changed my password just in case, problem still occurs.

i have checked my brave settings, cookies are set to block 3rd party.

i have now whitelisted youtube to allow 3rd party to see if this fixes

just curious if this is happening to anyone else and a fix is being developed?
