Following a successful dongle update my AIO inverter will not connect to my domestic Wifi. Each time the app connects but then shows “the app has cancelled the request to choose a device”. It seems to have a problem identifying the dongle (internal) type. It had no problem in updating the dongle but now it will not reconnect. I have followed the instructions to the letter and ensured the router is set to 2.4. What am I doing wrong?
