Hey, Everyone -I was having the same problem as everyone else after the update. I found a solution for my setup. Hopefully it will work for you, as well. Try these steps:
Open AirDroid on your device.Touch the user icon in the upper-right corner of the screen, next to the menu icon.Sign in using the same login process you will use on your computer, i.e. directly into AirDroid, using Google, Facebook, etc.Now open web.airdroid.com on your computer (and sign in, if necessary, using he same login as in step 3).
