How to use views contextual filter default argument "Taxonomy term id in url"
Have you figured this out? If so could you share your answer?

I do not think the problem is that the path follows any pattern.  As long as you create a path that identifies the location of a term and you configure the contextual filter correctly.  eg. example.com/whatever-you-want/any-term will work as long as the view path is example.com/whatever-you-want/%.  The 'any-term' must be a term in a vocabulary defined for the contextual filter and validation must be set to identify it.
