Octopus integration tariff comparison - one tarriff (Cosy) has stopped working

I have the Octopus integration set up. I currently use Agile. I have a graph comparing the electricity price each day of my current tariffs to three other tariffs - Cosy, Flux and Intelligent Flux. Since the 1st of October, however, the Cosy comparator has stopped working in that it always shows the exact same amount, whereas previously it varied by the day.

Have I missed something or is this a fault? I cannot see anything on the forum or in the documentation about this.

Going to assume you’ve already checked on the documentation here.

Also might be worth opening an issue on Github to help the developer, I’m sure they’d be thankful for that.
