Hi! When looking at my app under connecged devices, I am seeing duplicate devices with similar or the same names. Two different gaming consoles under devices that have been connected but there is only one in the home, that have the same name. And then also two phones with slightly similar names when there is only one. Is there a reason for this? Or should i be worried about someone cloning my device or neighbors on wifi or anything. Thanks!
