Can't plot one point with plotly() after running Pkg.update()

New to Julia

Hi there.
I used to be able to plot one point, say (1,1) with plotly(), in the following way:

using Plots
plotly()
scatter([1],[1])

but after doing Pkg.update() I get the following error:
“UndefRefError: access to undefined reference”

Can somebody help me fix this?
Also, if I do the same example but with gr() there’s no problem.
Thanks in advance.
Edit:
I went back to the older version of Plots with Pkg.pin and now plotly() works with the example above again.
