When updating the `Symbolics` package to its most recent version, I get a few other package updates and new packages. However, when running `Pkg.update()` immediately afterwards, julia downgrades ones of those updated packages and removes a package.

Any thoughts on why this happens?

The resolver has been updated in 1.7 so it should likely be fixed there.

One might say the issue has been _resolved_ (I’ll see myself out…)
