WD Access not visible with Cmd+Tab (OS X 10.11.2)

There is no application icon when switching apps with Cmd+Tab.
It does visible though with all-apps-on-the-screen mode (not sure how it is called on Mac - on my MBP it is shown with F3 key).

Hello,

Have you tried to re install the software to see if this way it shows up normally?

No, but I have updated it recently to the latest version.

try to uninstall the software and then do a new installation to see if that helps you.
