UI resets overnight, forcing me to refresh the page

When I close my laptop for the night and come back the following morning, and navigate to an open t3.chat tab, I find that it’s reset. I’m still logged in, but none of my archived chats are visible, it’s prompting me to “Make sure you agree to our Terms and our Privacy Policy”, and most importantly, my preferred default model is no longer selected. Instead, the t3.chat logged-out default is selected (currently that’s Kimi K2). I’m on Google Chrome 144, on macOS 26.2.
