iPhone 16 Pro Connectivity Assist setting keeps re-enabling on iOS 27

On iOS 27, Connectivity Assist is turned off globally in Settings > Wi-Fi, and I also turned off "Use Connectivity Assist" for my home Wi-Fi network about two weeks ago. Today, for the third random time, the per-network setting was back on for my home network, and I didn't change it.

The global toggle is still off. Only the per-network setting flipped back.

• Device: iPhone 16 Pro
• iOS version: 27.0.1
• Other Apple devices on the same iCloud account: yes

Has anyone else seen this? Is there a way to keep it off, or does the per-network setting override the global one?
