[sscots]

I'm trying to tag matches by spectator, and I know the match below had a spectator and it's not appearing in the match object.

Expected Behaviour

Spectators array should contain at least one reference

Current Behaviour

There are no spectators listed

Context

I'm trying to filter matches by spectator, after I've pulled them through the api.
Ideally, I'd also like to query the matches endpoint by spectator but I know that's not possible right now. It would be nice to have though.
