Update queue settings
Changes the account’s posting schedule. Send slots, timezone, or both; only what you send changes. slots is a FULL REPLACE (max 50 entries, one per unique time, each with at least one weekday, 0 = Sunday); [] clears every predefined slot and leaves the queue all-custom.
Changing slots also RE-FLOWS the queue the way the app does: a queued post sitting exactly on an occurrence of an old slot moves to the matching new occurrence (Nth old to Nth new), so deliberate gaps are preserved and hand-picked custom times stay put. Scheduled X Articles and chained quote posts never move. Changing only timezone never moves posts.
reflow.bailed: true means the settings were saved but the queue was deliberately left untouched (a post had nowhere to land, or the move set was too large); the response then carries a note. Retrying the same request is safe and idempotent.
Changing the timezone and the slots in one call usually moves nothing, because the existing posts were placed under the old timezone; to re-flow them, change the timezone first, then send the slots in a second call.
This is a per-account write: pass account_id for any linked or shared account. Editor-permission shares CAN change queue settings.
