Hi @LTownsley
I have seen this reported from time to time on both the Community and over on NOW Twitter.
Here's a recent linked thread below.

First thing I would try is a different Internet browser such has Firefox or Chrome or another browser device.
On the above linked thread I have also added a further link with the NOW Broadband Team telephone number where the helpline is open between 8am to 8pm.
