It was one long list in no particular order. What you already pay for, what you could buy today and what is not yet available to buy all looked the same and sat mixed together, so the page could not answer the first question anybody has. It is now in three groups: what is on your plan, what you can add, and what is available on request.
Prices are written as prices. They read “£49/month” rather than “GBP 49/month”, and two parts of the page that formatted them differently now agree.
One add-on was showing a technical error message as its status. If our payment provider was briefly busy, the raw message it returned was printed on the card, which read as though something was broken. That now says plainly that we could not confirm the price just then and to try again shortly.
Plain descriptions. The cards described the technology behind each add-on rather than what it does for you. They now say what you get.
