The “Account Closed” seems to be an account closed by staff from the backend, not a fpv.
Errors in Daily Team matches https://api.chess.com/pub/match/{ID}

"I get the impression the API is no longer of any interest to Chess.com"
I hope that's not the case as it's a very useful resource and it would be utterly short-sighted because I think many members are adding value to the site through a host of API related activities.

What is wrong with the country code one?
Seems to be working for me.

This seems to have been resolved now, perhaps only by the passage of time?
As for the other, I see the same inconsistency you do. As @ninjaswat said, it's probably about _how_ the account was closed.

It was resolved because the match started. The API continued to show incorrect data until the match status changed and the API was refreshed. After more than two days I would have expected consistancy between the web page and the API.
Found two significant errors in end point

Player @jim78 daily rating changed two days ago but is still incorrectly classed in this match as 'Out of rating range'
@dhalllawrence was FPV closed three weeks ago.
In these matches score is still show as the board finish and not defaulted to opposition win because game archive icon is shown as 'Account closed' not 'Closed: Fair play'

The match scores are inconsistant with the aggregated board scores.
Also still waiting for the country code login to be resolved after 6 months
