I have had Bitdefender for a long time and this year I switched to the family one to protect more devices. I have installed the program and did all the updates and yet my Bitdefender Central says the following:
This device isn't protected.
Install Bitdefender security on this device to keep it safe. It's already included in your subscription, so you can get it right away.
Enable protection
It says that it has been installed on one machine which is my machine so not sure why Bitdefender Central has this error under my devices.
