Trusted devices list is not available
Recently I have noticed that the list of trusted devices no longer appears under my Apple ID on both iPhone SE running iOS 14.0.1 and iPhone 5c running 10.3.3. After signing out of iCloud, restarting the devices, and signing back in, the issue persists. All devices are displayed under my account when I sign in at applied.apple.com.
After a quick chat with support we determined this was caused by my network. We verified this by disabling WiFi and testing over cellular data. When not on my WiFi network the list of trusted devices appear.
To discover what might be blocking this I logged into my router and put my devices on the DMZ, but the issue persists. My ISP is Verizon FiOS and the issue only started Monday. There were no problems before this.
Has anyone else seen this issue and determined the root cause? It’s not a huge deal, but I do find unsolved mysteries annoying.
iPhone SE, iOS 14
