Question Upgrading from mediation 0.5.0-preview.5 to Ads Mediation 1.0.0 causes multiple errors

I have mediation working on one of my projects, but I'd like to upgrade to the latest version. I'm a bit surprised that it breaks the code in a really unusual way. I have "using Unity.Services.Mediation;" at the top of most of my mediation related scripts, but after upgrading I'm told that this is no longer exists.

In VS Code it doesn't show any errors, but Unity does. What happened with this library and what I do to replace it? VS Code keeps telling me to use Unity.Services.Mediation to fix the error but Unity's console says that the Mediation namespace doesn't exist.
