Also, when I click on "full desktop site," it takes me there, but with the default forum skin, not Nightshift, even though I have that selected in my User CP and had it selected at the bottom of the page.
Unfortunately I do not know how to fix this one. It's a static link to the default desktop style. I'm not sure how to code it to make it go to the preferred style:-( You'll have to reselect, but once you've followed the procedure and disabled the auto mobile detector, it should not revert you to the mobile style after you've selected another one an a device. I looked at the code and it completely bypasses the mobile detection code as long as you are logged in and have that setting to YES=disable
