Bluos controller app ios

The powernode keeps getting itself kicked out of the bluos app… I have to switch the mains off and then switch on again for it to be detected back on the app. I have checked my Wi-Fi and it’s strong. There is no network issues at my end. The powernode is faulty or the wireless antenna has some issue. I can’t figure this out. It’s a hell of a lot of money and there is no fix. I tried writing to the support crew but all I got was an email that says my request received… It works for a few hours and then the powernode disappears from the app and I can’t control the amp anymore… And seems there is some integration issue with iOS. This needs to be fixed as I am not going to get an android phone just for this…
