Make the Creative Cloud App List responsive

Re: CC v. 4.8.0.421

MacOS Mojave

2012 MacBook Pro

When I click an app icon in Creative Cloud to open it, nothing appears to happen for many seconds. The icon shows no evidence of having been clicked. It's easy to conclude that maybe it needs a double-click - but nothing happens then either...

although, watching Activity Monitor shows that a single click does in fact launch the app, which then takes a long time to show any evidence of loading.

Please make the CC UI responsive.
