How to show docstring-based documentation in IJulia notebooks?

If I type ?[Function] in a jupyter notebook with a IJulia kernel, I can see IJulia searches for the documentation and it “finds” it, but it doesn’t show it :-/ :

Julia 1.4.1, IJulia 1.21.2

Works for me (Julia 1.4.1, IJulia 1.21.2):

Maybe you need to update your jupyter installation?

Thank you, but I have the latest jupyter from pip… and honestly seems something more julia-related than jupyter.

(yes, I did try different browsers)

I do have however some warnings when I start Jupyter:

Make sure WebIO.jl is installed correctly (try running Pkg.add("WebIO") and Pkg.build("WebIO") from the Julia console to make sure it is).
