Creative Cloud has been criticized for broken file syncing, one of its core features.[34][35] In May 2013 Adobe announced that it was suspending the file-sync desktop preview "for the next couple of weeks".[34] Reviewers of Creative Cloud were disappointed with the functionality of the cloud storage[36][37][38] and were "far from convinced by Adobe's subscription model".[39] Some users were concerned that they would be forced to upgrade their computer hardware when it is no longer supported by the current version of the Creative Cloud software.[40]
