Entity View Attachments (EVA) with multiple contextual filters?
Querying the configured multiple contextual filter isn't working as i expected first and I spent lot of time to figure out why, then finally the solution was found:

Instead of Content: The name of Taxonomy (taxonomy_vocabulary_#) you need to select Content: Has taxonomy term ID Contextual filter and enable Allow multiple values to able to use multiple values in the form of 1+2+3 (for OR) or 1,2,3 (for AND).
If You have another Contextual filter configured, you can separate the query with "/".
