Sorry about that I realized that I should have included. Details below. I know I don’t meet minimum requirements, but I have been able to get it to work before.
After my original post I also downloaded Roon for Windows and lo and behold, it worked. Audio is streaming.
And even more weird, after trying to music to play on my iPhone dozens of times, I played it through Windows and now it’s working on my iPhone. There were no changes in my Roon iOS settings.
Literally, would not work on my iPhone. Installed Roon for Windows. Played one song on Windows. Tried again the iPhone and it worked. So weird.
