How To Register XT8 routers

[lokiguy]

Detailed description：I attempted to register my new ZenWIFI XT8 routers (2 pack) and received a message that the serial numbers are invalid, using BOTH the MyAsus application and my Asus website account. How do I register these products?

Hello loki,
Please kindly share the SN in the PM I send you.
There should be a main SN on the box of the router, that represent the whole pack.
Thank you.
