IOS Nighthawk App not showing any devices in Device Manager

I have the RAX54v2 router and use the Nighthawk app for monitoring my households internet. I recently got a new phone and now when I log into the app, the device manager says there are 0 devices connected. If I click on  the device manager, it gives an error "Sorry, your device list failed to load. Please try again later." I have tried multiple times since i got the phone almost 2 weeks ago, but it always says the same. This transfers into the Security part of the app. Occasionally Ill get notifications about Armor blocking a site. When i try and open the notification though, it again says there are no devices being protected, despite showing there are threats being blocked. I tried logging out and back in. i tried deleting and reinstalling the app. Nothing seems to work. Any help is appreciated!
