Radar for past time is not weird. Radar is measured data - it’s not hindcast or a forecast. By the time the radar scans the sky, the metservice processes and put the data on their website, and RainViewer graphs that data and puts it in the composite image, and Flowx servers processes it (checks every minute) and Flowx app downloads the data (checks every 200 seconds), it can easily take 5-10 minutes.
So it’s extremely difficult to get real-time radar images - hence it will always be in the past and you cannot make it visible in the current time because that would be wrong.
I think the best option is that when you turn on radar and the time is ahead of the current time, Flowx will snap to the latest radar image.
In the future, we plan to predict the future 1-2 hours of radar - this is a prediction, i.e., a forecast, which will solve this problem.
