 * Plugin hasn’t been working since the 4.0.0 update for us. We’ve reinstalled it
   w/ each new update since then but have had to roll back to the 3.7.0 version 
   every time. When installed, the author name simply doesn’t populate. Searching
   for an author will generate the pulldown, but selecting th author does nothing.

 * The dropdown populating means the `/coauthors/v1/search/` endpoint is fine and
   the search-as-you-type wiring works. The “selecting does nothing” symptom points
   at the `onChange` handler in `src/components/co-authors/index.jsx:104-112`, which
   calls `addItemByValue()` and then `updateAuthors()`. If either silently fails,
   you’d see exactly this — search works, selection no-ops.
 * Most plausible causes, in rough order of likelihood:
    - **Stale bundled JS cached by CDN/browser** that doesn’t match the current 
      REST API shape (the `coauthorTermIds`/`buildCoauthorTermIds` rework in a recent
      PR changed the entity store contract; old JS would break here silently).
    - **A JS error mid-onChange** that’s only visible in the console.
    - **A third-party plugin filtering** the REST search response to omit `termId`
      or `userNicename`, which would make `addItemByValue` find nothing and silently
      no-op.
 * [@egonzaleztest](https://wordpress.org/support/users/egonzaleztest/) Please can
   you share your WP version, the full console error with stack trace, the active
   plugins, and whether your site has a CDN and/or object cache?
