Why do I get redirected by the browser to install MotionPro client when it's already installed on my Mac?

This is a known issue with the combination of the OSX Operating System (macOS BigSur 11.4) and the Firefox browser (89.0.2 64-bits).

This might occur when you visit the URL site for the VPN directly and log in.

To avoid this issue, launch the MotionPro client from your local system rather than accessing one of the VPN endpoints from a browser.
