Spark Max LEDs not in sync

Half of our sparks are flashing magenta while the others are still magenta but each is at a different speed than the others. What does this mean? And how can we fix it?

I’m not sure what it means, but if you power cycle, it tends to fix it.

videos can be very helpful for diagnosing this sort of thing if a power cycle and quick check of your wiring and firmware doesn’t fix things.
