Live view AGAIN!

Hi all , ever since I got my battery spotlight camera the live view has been shocking , either takes ages to load up or doesn't load up at all on either 4g or home WiFi , I can view an " event " no issues at all but live view is rubbish , my rssi signal is -42 so it's strong !! WiFi speed is approx 40mbps , I have split sky q router bands and it can only connect to 2.4ghz anyway ! Router is literally 8 foot away from the camera , even tried it with no wall in the way ( sat router on window ledge ) still rubbish !! I have reported this to ring and they accessed my account and said " everything " looks good and strong signal !!!! I've reset router and camera and latest app installed , tried the lite version, still rubbish !!!! Pics are of 4g and WiFi , Any ideas ???
