Essentially I can’t change stations using presets.
When adding iRadio stations to my favourites/presets they appear fine using the IOS app. However when I go to actually play them they rarely work most of the time and regardless of which station I press I keep getting the same 1 or 2 stations playing instead ie I’m playing 5Live then press Radio 2 it will show radio 2 as text playing but the logo stays in 5Live and it’s actually 5Live playing.
Try the app reset in ‘Settings’.
After that it might be worth clearing the iOS RAM - double click the home button & swipe up & off all the saved screens & then power cycle.
… oh err, maybe time for a whole system power cycle to zap what could be a confused/bad link.
Turn it all off, leave it for 5 mins so the ISP knows its off line. Turn on the wireless hub (router) first (let it finish) then NAS, then 272 & then the iOS.
