I am now unable to synchronise my settings in any of my CC apps, even though I am signed in and the program recognises that (if I go under the elp menu I am shown as signed in. How can I synchronise my settings? The last sync was done on 31 January and I've made changes since then. This kind of thing really is not acceptable - Adobe need to get their act together.
Edit: I just tried again after updating Photoshop CC, and I got the message 'Can't connect to Creative Cloud'. The plot thickens!
