[Solved] iPhone WLED App Does Not Discover Lights

First project. ESP32/Logic Level Converter/Max9814 Microphone. Flashed WLED Sound Reactive version. Powered up, connected via Windows PC, made appropriate WIFI alterations, and voila – I have lights. Everything appears to function exactly as expected. Awesome.
I have downloaded the WLED app to my iPhone 12. I am really struggling to get this functioning. I get the ‘Welcome’ splash screen and hit “+” to add a light, but ‘Discover Lights’ is unable to ‘discover’ my lights. I’ve tried both IP address and custom name. Suggestions?

Once I put the phone onto the same network as the lights, it worked perfectly. Duhhhh.
