Display block if content type has entity reference (tags) that contains specific term I want to display a block when a node contains a entity reference field when specific term is present.

I have tried numerous modules that did not work for me or perhaps I did not set them up right, term_condition token_conditions entity_field_condition (using the appropriate patch)

EDIT: it seems the term_condition works on a clean install after applying some pending patches on the issue queue.  So this probably is a problem with my installation.
The easiest solution is probably term_condition

Install/enable the module and then on the block layout of a certain block you will be presented with a term visibility setting where you can search for term that will be used as the visibility condition.



NOTE: Currently the module is incompatible with rules as rules has its numerous conditions on its own.  This issue has been reported here
