Maybe you've rejected a cookie or something or there's some blocker in the settings the browser no longer likes on a new.model
A cookie wouldn't do it. It could very well be a .css file didn't load or got blocked, I do have extra security on my home network... Locked like fort Knox, my other phone could have the file cached which is why it shows there. On a desktop I could look through the page code to see what's going on, Brave browser doesn't seem to let me. I would blame the browser, but page looks normal with same browser on old phone.
Not too worried. Everything seems to be working
