When I hit the "Install All" button for collections such as FX Collection 2 or V Collection 7, the installation of each plugin does not happen automatically. Instead, after the first plugin gets installed, the remaining plugins say "Waiting". But, there are no other plugins which are being downloaded at that time which would require any other plugins to be "Waiting". So, to install every plugin, I have to wait until the currently-installing plugin is installed. Then, for the next plugin, I have to hover my mouse over the "Waiting" button (which shows a "play" triangle/arrow upon hover). I then click the "play" button, and the plugin downloads and installs. I have to do this for every single plugin in order to install a complete collection.
