I can't seem to get any of the apps to get past the title screen.
I've tried on a couple of different PCs (Linux Mint 18.3) on different networks. With My Colony, My Starship, and Death 3D all will pop up the a new window as normal but will not get past the screen that says "Loading". I've removed, downloaded a fresh copy, and reinstalled the launcher. I've also removed the apps from the launcher and added them back with the same result.
The native client and HTML5 versions of the apps all work fine and everything worked normally under v1.1.8 of the launcher.
