Mobile version problems?

Has anyone else had problems using the forum on a phone? A member has sent me an email saying he has got locked on to the mobile version and cant get back to the classic version which he'd prefer.

Any suggestions would help him.

If I remember correctly, its really hard to find. Ill reset my browser history and try to find it again.

Nope I lied it was easy. Top right hand, downward facing arrow.

I am back. What happened was the password activation was sent to spam therefore was unable to log in with correct pswd. Thanks. Have had this problem before.
