It looks like you haven’t connected this installation/device to your avast account, but we can’t tell as we can’t see the home page of the UI (and I can’t read Polish or convert/translate the message text in an image).
It is easier to post images on the forum as attachments, so those trying to help don’t have to access third party sites.
See attached:
image1. What my UI shows in comparison to the one you linked to.
image2. My AvastUI home page shows, top right that the device it connected to my avast account.
