Wrong coordinates returned from S2CellId#ToLatLng?

[ST-Apps]

I need to extract Lat/Lng coordinates from a given CellId, but I'm having a slight difference netween the returned values and the correct ones, and I can't understand why.

The original coordinates are

47.678956162876,-122.12871664749933

while the CellId is

6093384589483442176

What I get back is

47.72217122031298,-122.12705319813203

Here's a little snippet of my code:

var cellId = new S2CellId(CellId).ToLatLng();            
return new Geopoint(new BasicGeoposition() {Latitude = cellId.LatDegrees, Longitude = cellId.LngDegrees})

Am I doing something wrong or is there an issue when converting back to Lat/Lng?

I'm facing the same problem. C2 cells end up overlapping or having gaps.

I can reproduce the issue but so far had no luck fixing it. I thought that this is my logic mocking with coordinates and changes precision.
