Erase the browser cache, for starters. You can also try with another one.
Are you properly logged in? Some vpn used?

What is certain - the problem is only yours.
I use a business network (under vpn), private network of two types (cable and 4G), neighborhood WiFi, 5 different browsers, plus two mobile networks on phones - Android and iOS, logged in or not, everything is fine....

I've never seen such an option in the settings, I'm just reading it now, but didn't you select something that shouldn't? Maybe "Default Thread Age Cut Off".
