In order to adhere to the guidelines, I added compat entries the project.toml of my package, but for some reason that I can’t figure out, the package Plots.jl is creating me a lot of troubles. If I specify a version then (no matter which one) then the CI fails systematically by telling me that an explicit requirements want another version:
ERROR: Unsatisfiable requirements detected for package Plots [91a5bcdd]:

I have tried every possible version compat without success.
Yet, I am able to install and use the package without problems … What could be causing this and how can I avoid the issue in the future?
