V7.5 U3 Connector- Any limitations?

Hi,

I've been reading the 75. Admin Guide trying to find if there are any limitation using the U3 connector. On the docs It states "It functions and appears to the end users the same as the installed version of

the AppPortal client." and "The U3 AppPortal client functions are the same as the installed AppPortal"

Is that true or are there any feature that doesn't work on the U3 connector?
