Hidden-phone not working

I'm using the Module Class Suffix to try to hide some banner ads, by using the recommend code hidden-mobile. However this isn't working.

Please see attachment and advise, thanks.

Where did you find information about this suffix? you can use notablet/nomobile or onlytablet/onlymobile suffixes.

I got those from using Joomla 2.5, they worked then. The new suffix does work,. thanks, except it doesn't work for the Topbanner position. I tested it, I moved a module, that was hidden on mobile (no mobile), in it's original position, it didn't appear on mobile, but it did when I changed it to Topbanner position.

Any help? Just to emphasise, the module is hidden in on mobile except when the position is top banner. It appears nomobile won't work on topbanner.

Could you give me URL to your website and tell which module have the proper suffix?

Hey

The top banner next to the logo is the one I'm having trouble with. You'll notice that the "Sponsored links" module on the bottom of an article is on for desktop but not for tablet or mobile (that's good), but I can't get this to work for the top banner.

Please set in module suffix field this value

' box notablet nomobile'

the space at the beginning is very important.

Solved! Greatly appreciated.
