Heating Activity stopped logging heating hours

Hello, I've had an issue with my app since yesterday. Although the heating has been on and the room graphs show this, the Heating Activity under Care & Protect has shown zero hours since yesterday, in both the written total and graph. My Android updated yesterday so I don't know whether his had anything to do with it. It's always worked fine before. It's annoying as it's making the average heating hours per day incorrect. Has anyone experienced a similar issue?

Same on iOS, so not Android specific.
