PetrolPrices.com

Hi All
I have set up a webpage Card for www.Petrolprice.com that work when I logon to Hassio from my Pc, but when I trying and use the Homeassistant app on my iphone I cant get passed the log on screen I keep getting asked for username and password. does anyone have any ideas

I’ve had success with relying on apps for this; and using Home Assistant to detect when I leave my house during the day; and to send an actionable notification to ask if I want to open my chosen fuel pricing app
