New install; web UI won't finish loading

I just installed Volumio, got it on wlan by editing the interfaces file, but cannot load the web UI. The WLAN is definitely up… The web UI appears, but I have an eternal wait cursor.

I found a suggestion to try service mpd restart on the console, but it didn’t help.

I also found some posts saying WLAN isn’t supported?

Should I try a command line update?

Any ideas?

Device: Pi 3 B+
uname -a: Linux volumio 4.19.60-v7+ #1247 SMP Thu Jul 25 14:14:19 BST 2019 armv7l GNU/Linux
Network: WLAN with DHCP
How I installed Volumio: with PINN which is a multi-os-installer like NOOBS for the Pi
