I got the latest address module (a la https://www.drupal.org/project/address). I also tried a few previous releases. I also cleared out composer (composer dump-autoload, then composer update), but still broken. I see that the addressformat stuff exists in vendor/commerceguys/ but i have NO IDEA how to hook it up.

I'll wait for your next release, as I am wasting hours not really knowing what I am doing. So so eager to get going with this, but don't think this is the right way.
Happy to help you with getting the install straightened out, as I seem to be running into everything that could go wrong.
