Chrome Remote Desktop Connection

So, I got my first Chromebook, an Acer C720, yesterday (i'm in love with the OS btw) and I noticed Chrome Remote Desktop was stuck at the 'Connecting...' screen that appears right before the part where you type the device's PIN. I couldn't found a fix anywhere and today I found the culprit fiddling with the settings.
I was getting this error because I enabled Click to play plug-ins, instead of running them automatically.
Go to chrome://plugins
Find Chrome Remote Desktop Viewer
Check [X] Always allowed
Alternatively,
Go to chrome://settings/content
Find the Plug-ins section
Check [x] Run automatically (recommended)
