RBR50: Orbi app returns "Unknown error." verifying security account.

I am re-posting my question in the hope that someone from NETGEAR will read this and reply.

I have an Orbi RBR50 running firmware V2.7.4.24. I recently purchased a new subscription to Armor and am trying to activate it.

When I log in to armor.netgear.com I land on the "My Routers" page which says "No routers associated with this account." If I go to the "My Subscriptions" page and enter my activation code, I get an error message that says "Activate a new subscription" and "There is no Netgear router with this type of subscription connected to your account. If you have a new router, please first connect it to the account by using your Nighthawk or Orbi app. If you already have a router, with a different type of subscription, please contact the support team."

When I try to use the Orbi app and tap the Security tile, it displays a screen that says "Verifying account information..." and then eventually an error message that says "Error" and "Unknown error." with an "OK" button. When I click on the "OK" button the app returns to the main screen and my router does not connect to my account.

I have read all of the suggestions on the community page that FURRYe38 provided (@FURRYe38 thank you for replying) but they have not helped resolve the problem.

One of the specific suggestions listed is to enable and disable "Anywhere Access". I have done that and it has not resolved the problem.

I am still left with my question:

How can I correct the "Unknown error" when I tap on the "Security" tile in the Orbi app?
