Check your wifi to see if you’re on a 2.4Ghz signal, or 5GHz. The factory remote seems to conflict with one, or the other (I don’t recall which, but doing so cleared up my factory remote issues).
Wi-Fi Radio Frequency Interference (RFI) is what I suspect is garbling the remote signal reception.
So try switching your buzz box to another Wi-Fi frequency... if you can... some newer “smart“ Wi-Fi gateways don’t let you, unless you can manually override their default settings and squawk 2 SSID’s - one on 2.4 and one on 5.0.
Failing that, the ARQ remote mentioned in this thread uses Bluetooth and it seems to be more immune to competing Wi-Fi RFI.
Your mileage may vary.
