I've recently subscribed to CC, Lr and Ps. I have Lr 2015.6.1 and Ps 2015.5.1.
I'm running an iMac recently updated to OS Sierra.
I'm getting notification of updates being available but on opening the Creative Cloud app it either crashes immediately or opens with a blank lower screen. On selecting 'check for app updates' on the settings gear wheel nothing happens.
Is this a common Sierra issue or does anyone have any suggestions?
