DSC-RX100m7 cannot register extended 1 year support

[elaherd]

I can register my new dsc-rx100M7 for the 1 year extended service plan.  It does not appear on the list (latest model on the list is M5) When I type in the model number manually it will not accept it and the whole page is then cleared of all my inputs.  I have contacted Sony Support via email but all I got back was how to register my product (which I have already done!  Please advise the way forward.

I had similar but not identical problem. I found changing the browser to ms edge worked for me.
