Model Name: iPhone 16
Software Version: 26.3.1
App version: 2026.1766

**Home Assistant Core Version**

**Describe the bug**

I am receiving this same issue on iOS 26.3.1 on all of my thread devices. I cannot pair them with the Companion App. I have factory reset them and tried multiple times.

**To Reproduce**
Pair a thread device on iOS 26.3.1.

**Expected behavior**
Correctly pairs.

**Screenshots**

**Additional context**

There is an Apple TV Thread network near by that I don't control and credentials on my phone (debugging->thread) I cannot delete (ha-thread-ccb6), however it is using the correct preferred network (ha-thread-ccb6) as shown in the logs.
