Portal nota accessible from Chrome for iPad

Hi everybody,

I saw some other thread about this argument but in none of them the solution is very clear.

When I try to connect to my portal from Chrome on an iPad I get the following error...

Could not open iView. The iView is not compatible with your browser, operating system, or device. Contact your system administrator for more information.

Clik here to view.

I saw is an useragent problem. Does anyone knows how to fix it ? And make the portal accessible from any browser ?

Thanks,

Enrico
