Problem: I am using a View of taxonomy terms ordered by custom field value to show links to the next and previous term archives. I would like to filter those Views by term grandparent, so that only terms in the same grandparent are included in the results.

Solution: There is no term grandparent filter, so you can use another custom field in the Class Parts taxonomy. For each class, use a different field value. So for Knitting Superstar and all its descendant terms, use "knitting-superstar". For Fearless Knitter and all its descendant terms, use "fearless-knitter", etc. Then add a filter to the Next and Previous Views that filters by this custom field, set by a shortcode attribute. In the View shortcodes for the Next and Previous View, use a Types termmeta shortcode to insert the current term archive's custom field value in a shortcode attribute.

Problem:

I created a view to try to show the taxonomy terms with a parent that is the archive shown, but nothing shows.

Solution:

The problem is in taxonomy view:

in section "Query Filter", there is another extra filter:
Taxonomy is set by the page where this View is inserted

In your case, it is not needed, you can remove it and test again.
