I have never really understood why some gadgets seem to require  5g to be turned off so that the 2.4g can connect. I have had to do this with several items in the past eg Ring doorbell, ener-j smart sockets. Once they are connected you can turn 5g back on and they continue to work ok. You would think that if they do not support 5g they would just automatically connect using the frequency that they do work with
