WARNING: Calling the .opts method with options broken down by options group ... is deprecated

hvplot=0.8.0, holoviews=1.15.0

I'm trying to help a user here https://discourse.holoviz.org/t/interactive-and-dynamically-created-dict-of-widgets-to-xarray-sel/4000/5

When running the below code example I see the WARNING

WARNING:param.main: Calling the .opts method with options broken down by options group (i.e. separate plot, style and norm groups) is deprecated. Use the .options method converting to the simplified format instead or use hv.opts.apply_groups for backward compatibility.

So I believe something in hvPlot needs an update. But I don't know where.

Please note the log seems to output every message twice with a different format. That is a bit of friction that would be nice to remove.

This is properly https://github.com/holoviz/geoviews/issues/576 which is causing the issue.

Can you try to remove all the geo features from the plot to verify it?

[MarcSkovMadsen]

I removed the geo stuff (see code below) and I no longer see the warning.

I'm running geoviews=1.9.5
