I've paid $10 for the 6-month subscription to CCleaner Professional for 5 devices (PC, Mac, or Android) includes Kamo’s VPN-powered privacy protection + 24/7 live chat technical support and my serial number is not working when I try to activate it on my android phone app. It's telling me "Sorry, activation failed". Why is my Windows software serial number not working on my Android phone?
This is a user forum and we have no access to licence information, so for licencing issues we have to point users to support.
In this instance as you say that you have paid for the 24/7 live chat technical support then have you asked there?
