Sentinel-1 showing exact same image on different days?

I’ve noticed this recently.

I was looking at an area, and the S-1 image on February 21st and March 4th were exactly the same.

Is it a bug?

Dear @Space,

I checked a few location and found differences in the acquired images so can’t relay to what you are reporting.

As S-1 is taking thousands of images around the world each day, you need to be more specific. How did you obtain the data, on which location and at which bands/polarizations were you looking?
