Multiple devices not working

Hi!
I'm owner of 2 android devices - phone and tablet. Tablet is ASUS Transformer Infinity and phone is Xperia J. I can't get AirDroid working on both devices at the same time... When I go to remote desktop in Chrome in my PC, AirDroid connects only to the device that was logged in lastly. When I log on my tablet, and then on my phone, AirDroid in Chrome shows only my phone. And vice versa, when I log on my phone, then tablet, then web app shows only tablet. Was this intended by AirDroid developers? Can I get both devices avalibale in web app at the same time?

Thanks in advance for any help
