How to enable mobile version of the forum?

I accidentally chose the desktop version and now I can’t find a way to go back to the mobile version. Is there an option somewhere?

There’s a link down at the bottom of the forum main page, at least on my iphone.

If the link at the bottom doesn’t work then just wait a bit.

I never ever want the mobile version yet every week I seem to get it foisted on me and I have to go switch back to the desktop version.

Weird.

On the mobile version there is a button but in the regular version there’s no option for it.

Clear cookies maybe

Weird, left it for a few hours and it’s back to the mobile version.
