I cannot get WiFi upload to work anymore. I have turned off the iOS ip privacy settings. The app still shows the friendly name rather than the ip and shows no port. I did try the ip:1111 anyway but no luck. I also tried to contact support but the form wouldn’t work.
RESOLVED: Weirdly you have to turn “Private WiFi address” on for it to work

This app works very well and allows me to have complete control over my audio files.
