On iPhone 18 Pro models, Apple slimmed down the cutout where the Dynamic Island lives, allowing the latter to support up to three simultaneous Live Activities. But it turns out there's a catch. As noted by code explorer pdfu, the third Live Activity in iOS 27 is only ever a system activity, such as Now Playing or navigation – it can't be another app. So if you own a new iPhone 18 Pro and were wondering why you hadn't seen as many Live Activities in the Dynamic Island as perhaps you were expecting, that's why.
