Thanks everyone for the suggestions. I got the darn thing to work! It was a combination of user error & bad instructions. Instructions say to include it into the network, tap only once. However, it required double tapping the switch. Just to be sure, I grabbed a 50ft ethernet and set up the hub directly next to the switch, then set hub to exclusion mode in the app, tapped the switch, nothing. Double tapped, instantly comes up device removed. Went to Add Device, double tapped the switch, added right in. I feel stupid for not trying to double tap it the other day, but it clearly states press it once. sigh C’est la vie. At least if any other person has the same issue and strictly adheres to the instructions, they’ll have a thread to find the (painfully obvious yet somehow alluded me) solution. haha
