the pro was given to 8487585 UID , on your phone , it shows you did google sign in. if you want to use that google sign on netcut Pro, you can sign in this at the same phone where shows the UID as 8487585 , the Pro membership will then be transfer to your google sign in.
let me know if you need help manually transfer it.
I would try this
try to use old netcut 2.0 version to change your MAC address to one of the attacker’s MAC address. and change your windows device name. this should keep your ID away from their scan.
also, the attacker looks using fake MAC address.
there are plan that we release a version to hide your device all together from the network. not now.
