CCleaner Pro does not clean automatically.

CCleaner for Mac
1

I put option to clean automatically if CCleaner will save more than 0.1 GB of disc space,

but it does not work at all. Actually I bought PRO because of this feature. Dissapointed.

As you bought the Pro version this entitles you to support direct from Piriform.
