REST API returns 404 error for October 29th

In my app I retrieve the daily weather for a location via the REST API. This works fine in almost all cases. However, for October 29th (yesterday) it returns a 404 Not Found error. This is an example request that fails: https://weatherkit.apple.com/api/v1/weather/en/48.1582271841334/11.5418646663957?dataSets=forecastDaily&dailyStart=2023-10-28T22:00:00.0000000Z&dailyEnd=2023-10-29T22:00:00.0000000Z

I have also tried to append the timezone &timezone=Europe/Berlin - but the problem persists.

Maybe it has to do with the fact that Daylight saving time ended yesterday at the location requested (Germany)? It certainly looks like a bug. Where can I report it if this isn't the right place to do so?
