Tile is a little bit off

Hello!

I’m comparing a polygon between August 11th and August 16th. I have 3 images : 11th, 14th and 16th. The true color image versus the polygon position is not exactly the same on August 14th.

You can see the image

Here’s the geojson polygon:

geojson 
{
  "type": "FeatureCollection",
  "features": [
    {
      "type": "Feature",
      "properties": {},
      "geometry": {
        "type": "Polygon",
        "coordinates": [
          [
            [
              -72.61257469654083,
              45.73771694446185
            ],
            [
              -72.61188268661499,
              45.73771694446185
            ],
            [
              -72.61188268661499,
              45.738136277988225
            ],
            [
              -72.61257469654083,
              45.738136277988225
            ],
            [
              -72.61257469654083,
              45.73771694446185
            ]
          ]
        ]
      }
    }
  ]
}

Any idea why this is happening and if there something we or you can do to adjust this?

Thank you!

Sentinel-2 data are not perfectly aligned.
