Help by installing Avast theft on my phone

Hello forum readers,
I made an account and downloaded the programms from avast. As you can see my registration succeeded so I can enter the forum. But now I get the message that no device (so also not my phone) is connected to this anti-theft programm. Any body knows what I have to do now?
Help much appreciated :slight_smile:
