Hello RbirdNC,
Thanks for reaching out in Apple Support Communities.
We understand that your iPhone 12 and iPod are not showing your list of trusted devices even after updating the software version. We'd like to verify if your devices appear on the website as well. Here's how to check:
"Use the web to find where you're signed in
From the Devices section of your Apple ID account page, you can find all of the devices that you're currently signed in to with your Apple ID, including Android devices, consoles, and smart TVs:
- Sign in to appleid.apple.com,* then select Devices.

2. If you don’t see your devices right away, click View Details and answer your security questions.
3. Click any device name to view that device's information, such as the device model, serial number, OS version, and whether it's a trusted device that can be used to receive Apple ID verification codes. The information might vary depending on the device type."
More info here: Check your Apple ID device list to find where you're signed in
If all of your devices are listed there, restart your iPod and iPhone to verify if you continue to receive the same error message. Completing this step refreshes your device and the software:
• Restart your iPod touch
• Restart your iPhone
If the issue persists, we suggest that you reach out to Apple directly. You can follow this link to connect with them: Get Support
Also, in order to access your Safari data across your devices, be sure you’re signed in with the same Apple ID. If you have devices where you’re not signed in with your Apple ID or that have the Safari feature turned off, your Safari data will not sync across your devices.

All the best.
