This is from @TVSportsUpdates on the social media site that shall remain nameless:

Viewership for Friday night's MLS doubleheader on Fox, the first games on the network since the league's return from its World Cup pause:

• Nashville-Atlanta: 587,000 viewers

• Galaxy-LAFC: 504,000 viewers

Given what we've seen reported for Apple TV numbers (e.g. 75% of MLS Cup Final viewership was on Apple), that would likely bring this number to around 1-1.5m viewers. Not exactly lighting the world on fire, but a considerable jump.
