Unable to install from branch

I know that I have done this a million times, but right now attempting to go for the unreleased version using this: julia> Pkg.add(url="https://github.com/SpeedyWeather/SpeedyWeather.jl", rev="main", subdir="SpeedyWeather") gives me all sorts of errors related to the version of SpeedyWeatherInternals which was my way into the mk/heldsuarez branch, but I cannot even get the first step to work. while doing this throws no errors, but also does not move me away from the released version. I am still at 0.18.1 (@v1.12) pkg> add SpeedyWeather:SpeedyWeather#main What am I doing wrong? Why can't I install the latest unreleased version?
