Firstly, what browser do you use? Chrome will have a feature called "Always request desktop mode", make sure that isn't checked.
Secondly, as I'm sure you've already done, you'll disable infinite scroll from settings to opt out and change the view from settings.
There also should be a fairly big box on the page as well that says [Mobile Website] tap that.
Hope this helps.
Also don't forget when on the phone to keep the former unchecked and check the second one.
