If a fixture has both prematch and live coverage, will we get 2 fixture_change messages with changeType=new with product=1 and product=2?

Or will we only get 1 fixture_change message with product=2?

The fixture_change message with change_type="1" (new event added) should only arrive from producer 1 (prematch). If the match fixture does not include liveodds=”not_available”, it will be by default covered in both prematch and live.
