How teams should use this matrix

Treat the matrix as a preflight checklist before production automation. Account type, OAuth scope, media container, and publishing method can all change the outcome even when the same caption and file are reused across networks.

When a destination fails, compare the recorded platform error with the row for that network, then inspect Post History for queue stage, retry count, and whether the media URL was still reachable at processing time.
