Ok. The strange thing with the spatial dimensions is, that the new syntax forces the user to tell exactly, on which dimension the mathematical operator for resampling (like sum) should be applied. The syntax is now data.resample(time="M").sum(dim="time",min_count=1).

That weird - two times giving the dimension. However, doing so the xarray is not summing up for, e.g. the first month, all values he finds in a specific dataaray, but only those values along the dimension time.

AND NOW, the good new is that I got the following picture with your 'min_count=0' and 'min_count=1': 

{
    "total_count": 0,
    "+1": 0,
    "-1": 0,
    "laugh": 0,
    "hooray": 0,
    "confused": 0,
    "heart": 0,
    "rocket": 0,
    "eyes": 0
}
