Unable to activate subscription on auxiliary XG430 that's in a active-active configuration

Hi All,

Firewall Model: XG430, HA Active-Active

Software version: SFOS 17.5.9 

I recently renewed my subscription for my firewall. I was provided a license and told to load the license.

I proceed to load the license to my primary firewall, via System > Administration > Activate Subscription > Put in the license key > click verify and confirm loading the license. The license loaded without issue on the primary firewall.

I then proceed to login as the admin to the auxiliary firewall and repeat the same steps. However when i click the verify button, I am hit with and error message saying "You do not have the privilege to add/modify the configuration"

Am totally stumped at this point. If anyone can help or has experience with this I would really appreciate it!
