Audio check: Play back 30 sec right after going live. Muffled or silent? Check the Lava mic 3.5mm jack isn't fully seated.
Hotspot before GameChanger: Connect the iPad to the Nighthawk before opening GameChanger or it may stream over cellular and drop.
Shade is everything: Both the EcoFlow and Hotspot will throttle or shut off in direct sun. Under a chair is perfect.
Foul ball check: After any hard fence hit, verify the field view on the iPad. Pointing at sky? Walk to the fence and re-adjust.
Setup time: First time ~15 min. After your second game you'll have it down to 8. Steps never change, just the speed.
Battery backup: Orange battery is Plan B. If EcoFlow is dead, swap to it — same cable, same port, same result.
