iOS App not working

With the fantastic support from Michelangelo I implemented my volumio primo today.
A couple of issues still open:
iOS App not working at all (App does not find the device).
Volumio Web Browser not accessible from iPhone at all
Does anybody experience that kind of issues?
Thanks for your support

I have had this issue before on numerous occasions, sometimes I have to click retry a few times, sometimes I have to go in airplane mode and reconnect to WiFi.
