The reason there is no data now is that it takes time to process the data. The radar has to take the image, the met service has to process it, then put it on their website, then RainViewer has to process it and add it to the next 10 minute image, then Flowx has to process it, and then you have to download it. I’m surprised it’s only 10 minutes late.
If you showed the most recent data, which might be 10 minute in the past, at the current time, this would be deceiving.
If you are ahead of the most recent radar time and you turn on (or off/on) the radar, it’ll snap to the most recent radar time.
