Speed cameras not showing or warning at all now in the UK

So recently Waze has just stopped warning of speed cameras or even showing them on the map (both when I have a destination set and without) and this is going along routes that have always had the speed cameras marked on them. I don’t understand why I don’t get warnings, all the settings to warn me are turned on to the best of my knowledge (specially looked at speed camera alerts and they are toggled on)
