Since yesterday (Monday) afternoon, the Trello desktop app will not allow me to sign in on either of the two Mac's that I have (a Macbook Pro and an iMac). I get a sign in screen, it allows me to enter my login info, but then loops back round to the sign in process again. As a side note, I am able to sign in on the iPhone app and within browsers on my Macs. Can anyone suggest why this may be happening? Thanks!
