So...
On my dashboard I have my Octopus account linked through the API and the usage graph shows the correct outgoing rates, changing every half an hour. But on 22nd June it changed and shows 51.57327p for every half hour slot.
Then on 1st July this changed to a constant 30.8994p. I did get a price drop alert from Octopus so I'm assuming (hoping!!!) that this is a problem with the API - or have Octopus changed their tariff rates?!

Anyone else have this issue / know whether it is an API problem / Octopus rates for import are now fixed on Agile Outgoing Octopus?

Thanks!
