Link_selection with hvplot (scatter) and hvplot.points (lon,lat)

A geographical object created via
geo = df.hvplot.points(‘longitudes’,‘latitudes’,geo=True, tiles=‘OSM’,color=‘red’, alpha=0.2,xlim=(-130, -60), ylim=(20, 60))
This displays fine as stand alone.

scatter = df.hvplot(x=‘x’, y='y,kind=‘scatter’,responsive=True,min_height=150)
This display fine as stand alone.

However when I do
ls2 = hv.link_selections.instance()
ls2(scatter) + ls2(geo)

returns an error “AttributeError: ‘WMTS’ object has no attribute ‘_transforms’”.

Tried with conda installs + pip installs and both yield the same error.
Any thoughts ?
Thanks in advance
