Hi Mosca Bianca,
Lightroom Mobile is included in the Creative cloud subscription however, if you are not willing to go for Lightroom Mobile, you can pause the syncing through the dropdown menu on top left under the identity plate.
Thank you VERY MUCH for such a quick and helpful reply. I have done as you suggest and it works! I am just wondering how to remove my photos (already synced) from CC..
This quick and very helpful answer has solved my sync problem. Thank you very much. I just need to find out how to take the photos already synced out of CC..
There must a new row under your Folder's panel with the name "Ipad/Iphone"
You need to select it > right click and choose remove (dont choose delete from disk, if you receive that option)
