Can't pair with Xenon during setup

I got a Mesh WiFi Bundle from Adafruit. I set all 3 up when I first got them, but due to some issues I had, I recreated the network. I only added one Xenon to the network, now I am trying to add the second one but I can’t even get the app to pair with the Xenon.

Edit: I should also mention I upgraded the Argon and the Xenon that is on the network to 0.9.0, but the Xenon that won’t connect is on 0.8.0.

Restarted my phone, seems to have fixed the problem. The app paired, initiated an update, etc.
