Two different Macs are depicted as one computer in the account

Hello!
I've installed AdGuard on a clear MacBook (it was previously used by me, and I'm handing it to my mom now), and AdGuard starts working without any actions needed. When I revoke the license on another MacBook and update on the first one, it stops working. When I login into my account, two MacBooks look like one, so they're kind of interconnected in terms of AdGuard license.

I will use 'MacBook Air' (an old one; I used AdGuard there before, but I've formatted the disk and reinstalled the system) and 'MacBook Pro' (the one I use now, kind of a new Mac of mine) below.

### Steps to reproduce

1. Install AdGuard on MacBook Air. It starts working with no license activation needed.
2. Reset license key on MacBook Pro. 'Refresh status' on MacBook Air. It stops working.
3. Enter license key/login to account on MacBook Air. In the web account it looks like MacBook Pro, the same name of the computer.
4. 'Refresh status' on MacBook Pro. It works again.

### Expected behavior

I believe they should act as different computers and mustn't be interconnected.
