Hi! Changes to permissions enforced by Google in Android 6 prevent CCleaner (and other cleaning applications) from performing automated cleaning of application caches. As a result, they now need to be cleaned manually. Just to note, CCleaner can still clean other items from the device (Downloads, APKs, Ad cache, etc). Googles policy on this is unlikely to change in the short term, and will continue to affect all apps with similar functionality. However, we remain committed to further development of CCleaner Android, ensuring it remains a valuable addition to your Android device.
