Moz.com is reporting that many URL's are to long, these particularly affect Product URL's where the URL is typically https://www.domainname.com/collections/category-name/products/product-name, (You guessed it we're using Shopify).
However, we use Canonicals that ignore all most of the URL and are just structured https://www.domainname.com/product-name, so Google should be reading the Canonical and not the long-winded version.
However, Moz cannot seem to spot this... does anyone else have this problem and how to solve so that we can satisfy the Moz.com crawl engine?
