Router randomly removed, can't re-add to Cloud Portal due to page malfunction

[Crash_HI]

Greetings,

Netgear Insight periodically and randomly removes our router from the VPN group. I need to re-add it, but the Netgear Insight portal web site displays a blank page when I click on the Router/VPN tab:

https://insight.netgear.com/#/routers/quickview

It is therefore impossible to enable VPN functionality.

I am an Insight Premium subscriber and a VPN services subscriber.

Thanks
