Cant go back to mobile version

I have a link on my mobile site for desktop version for users who would like to see full version. Once they goto desktop version, they cant go back to mobile site until they clear their cache. 
Is there any way to solve that issue?

??

I have this same problem running latest version of mobile joomla and flat template. Any ideas?

You can publish Select Markup module in one of position of desktop template (there is a special instance of this module that is published in "footer" position by default).
