@beanbag It may be a script/cookie that is keeping you “logged in”. You can open a New Private window, enter the url, and if you don’t get the same behavior, that is a good indication it is something the site downloaded when you allowed cookies and/or disabled block scripts.
You should try clearing browsing data for all time at brave://settings/clearBrowserData. You can use the Basic tab and check all the boxes. That should clear the saved account information.
If you don’t want to clear you browsing data for some reason, you can go into Site and Shield Settings at brave://settings/content. First select Cookies and site data under content and delete the site from the allow cookies list. Go back and click on Javascript and delete the site from the allowed to use Javascript list. If you are unfamiliar with what I am saying and need more information (paths & screenshots) just let me know and I will go into more detail.
Please post an update. I think this will work but would really like it confirmed (or not)! Take care.
