S50+ no longer seeing any wireless networks

I have 2 S50+ units and I love them. A couple of days ago one went into setup mode unexpectedly. I connected to it using wifi and tried to set it up. It can no longer see any wireless networks - the list of networks to select from is blank. How do I proceed?

I found that if I turn off my cellular data connection and just use wifi on my phone things work. I’m guessing that when I attach to the Arylic access point there is still a routing issue and communications are being directed over the cellular network instead of the wifi connection from my phone.
