After 20-30 minutes of reading posts, I'm automatically logged out. I would still get the option to reply but on the reply page, it would say I'm signed out.
It's frustrating. I use Edge, Chrome, Brave, and OperaGx. I've also used Linux and Windows 10, but it didn't fix the odd login loop. So far, the "best" possible fix is to just close out the browsers and log back in. It's a duct-tape fix but I'd assume the cookie or cache management has some issues in this site.
