Definitely seems to be an iPhone 16 issue. 18.2 DB3 has not fixed the issue on my iPhone, but an iPad and Mac all display the stickers correctly. Sadly, I tried deleting all of them in the hopes that the database would rebuild, but no luck. Phone is still showing useless gray circles.

This feature has made networking a nightmare for places like hotels who rely on consistent identification of a user device to provision it for Wi-Fi access. The documentation on this is lacking. There isn't any specification as to exactly when the MAC address will be rotated out. Is it 24 hours, then automatically changed? Is it 24 hours, but it keeps the old fake MAC address until you disconnected from that network and reconnect? Is it 24 hours, but you have to be disconnected from the network for a certain amount of time before it rotates the MAC address? Is there any event that an app could use to determine if this rotation happens? With that, you could notify a user that they have to re-pair or sign into the Wi-Fi again rather than having them frustrated when things don't work right. Why do some networks display a notice that this isn't supported? What is the determination for that?

It will break. I have static IPs set up for my devices and this new feature kills that when the fake MAC address rotates. Unless you're doing something really fancy like Hotspot 2.0 on your gateway, it is dependent on the MAC address to identify the device. Once that MAC address gets changed, your device appears like a totally new/different device to the gateway/router. The 24 hour thing seems to be broken in the new betas for some people. It wasn't 100% clear on when that cycled anyway. Was it 24 hours, then changed? Was it 24 hours, but it kept the old fake MAC address until you disconnected from that network and reconnected? Was it 24 hours, but you had to be disconnected from the network for a certain amount of time before it rotated the MAC address?

This feature will cause a lot of grief in the hospitality industry. Hotel Wi-Fi connection is just one thing that may rely on the MAC address for identifying a guest. Once the device's MAC address changes, anything that used an IP address or MAC address to identify a device will be broken. Door lock access, guest device for loyalty interactions, casting content to the hotel TV, casino membership, etc. This randomized address will force developers to store additional information about a guest's device in order to keep things functional and secure. I would rather not store other information or force a user to take additional steps (re-sign into Wi-Fi, scan a QR code, tap NFC, etc.) to keep them associated with the amenities available through their account/stay. If the 24 hour refresh could be extended or optionally set to a value (1 day, 1 week, 1 month) by the user when joining a network, that would help alleviate a lot of the issues this new privacy feature will create.
