Cant show Commerce Products in View on Taxonomy Term page
This isn't an official source, but it might help you.

Don't attach a block on your taxonomy page. Instead, create the View as a page and set the URL (under path) to override the the taxonomy term page (e.g. taxonomy/term/%).

Under contextual filter use : Content: Has taxonomy term ID

For the filters, use the settings in the screen shot (in the screenshot, my taxonomy terms belong to a vocabulary called Shop Categories).



Hope that helps!
