Current Behavior

PitStopSeries is never received live, so sensor.f1_live_drivers_pit_stop has the correct count for every car but stops: [] all race long (no lap, pit lane time or stationary time per stop).

Integration diagnostics during the 2026 Singapore GP race (F1TV token valid, used_for_live_timing: true):

signalr_stream_capabilities.active_live_streams: [..., "PitStopSeries", ...]
signalr_stream_capabilities.auth_gated_live_streams: ["CarData.z", "ChampionshipPrediction", "DriverRaceInfo", "PitStopSeries", "Position.z", "TeamRadio"]
live_timing.streams.PitStopSeries:          {"frame_count": 0, "last_seen_age_s": null}
live_timing.streams.CarData.z:              {"frame_count": 7281}
live_timing.streams.Position.z:             {"frame_count": 7077}
live_timing.streams.ChampionshipPrediction: {"frame_count": 90}

So other auth-gated streams arrive on the same connection, only PitStopSeries stays at 0. Diagnostics saved during Friday and Saturday live sessions show the same 0. Meanwhile the official static archive of the same race contains 25 PitStopSeries messages, and in replay mode the stops list is filled correctly.

Expected Behavior

The stops list should be filled live as it is in replay. Do you receive PitStopSeries live with your setup? If F1 only delivers it to some subscriptions, a note in the docs (or a fallback) would help.

Logs

No error is logged.
