Wyze plug offline after setup

I spent quite a bit of time with setting up a new set of Wyze plugs yesterday, and no wifi network was recognized. This morning, there was an update to the IOS app, and it allowed me to set one of the plugs up successfully. The second plug appears to setup, they just shows as offline. Tried to remove and redo it several times, it even worked briefly, then back to offline. I think it’s safe to assume defective hardware?
