Wrong Explanation -
The description how to clear your Creative Cloud https://helpx.adobe.com/de/creative-cloud/kb/file-storage-quota.html does not match with the actual design of the cloud. Therefore, there is no useful explaniation how to clear your cloud. I deletet all pictures but does not get access to the cloud. That's really annoying - and it is not self explanetory. That's a shame. Handling the cloud should be much easier.
