It is exactly what I tried to highlight... When data is not available (outage or other) for a given timestamp, it should not be displayed on map... Satellite image validity should be the same as the timestamp on timebar (+/- the minutes delay Windy uses to interpolate the worldwide mosaic).
Old validity images should not be displayed here, otherwise info on West side would be false (actually, kinda choice to be taken between "beautiful" and "correct" data layers :o))
