@mxnrg here is a tip from another member re the Wi-fi etc. Did you do the update. He explains it helped the clunky app.
“ The App. In a word 'clunky' as others have said. Initially I couldn't achieve a wifi connection (Iphone 5s). I found the answer was to set the wifi in iphone settings to the UTR signal THEN start the app. If you have the app already started it just never gets to the first step which is to prompt a change from the generic password. So, having changed the camera SSID and password and the security protocol to that prompted by iphone I was in! Changed a couple of other settings to my requirements (not essential) and then was prompted to do a firmware update by the UTR app. Takes about 5 mins but all went through OK. The App then became far more responsive which probably explains the initial clunkiness. All cameras and initial recordings checked and OK for position / picture quality”
