User level: Level 1 (9 points)My Apple Watch series 9 keeps messaging me that it is opening an iPhone that was traded in long ago. Should I be concerned?

On the iPhone, go to Settings -> Face ID & Passcode ->Unlock with Apple Watch and make sure only your current Watch is enabled. Also check Watch app -> My Watch -> All Watches to confirm the Series 9 is paired to the correct iPhone.
If the old iPhone still appears anywhere under your Apple Account/Find My, remove it if you no longer own it. Apple also recommends checking your devices when moving an Apple Watch to a new iPhone.
