no detection(no menu) after choice

With first install all works fine, detection and templateswitch. But then i click with my smartphone at bottom on the desktop-link the standard-website appears, but how switch it back to mobile-mode?
the link dissapeared; same with different mobile-testingwebsites.
Whats to do to bring the link back?

- still tried putting /?device=auto to url and deleting cookies, no effect

maybe you should add "Select Markup"  module to your site.

I have the same problem: people who choose the standard version can't rollback, and someone didn't mean to usethe standard version... I just want to force, no coice!
