V10 PLAYBACK DIAGNOSTICS / AVAILABILITY TEST
Paste YouTube URLs, video IDs, or song searches one per line. V10 tests the actual embedded player, remembers blocked/verified video IDs, and can search deeper for a playable replacement when you choose. The original YouTube video is always one click away. For a song name, use Artist - Title; the API key is required for search lines.
No test running.
PASS means the YouTube embed reached a valid cued/playing state. FAIL records the YouTube player error. UNKNOWN means no conclusive response arrived before timeout.
Diagnostic player idle.
No V10 batch recovery run yet.
