Try enabling the guest network on your router. Enable only the 2.4G band for that network, and try to connect those three switches to that network. User a different name and password than your main.

@Tony , thanks for your reply.  The issue is connecting it to my phone prior to connecting it to the network.  

I was able to get the device to show briefly, but it then disconnects before Kasa can pick it up and assign to my network. 
 

I get the following and it's happening on any switch I reset.  Not sure if it's iOS 14 or something else.  

@Bdubs 

With the new iOS 14, might be, do you happen to have another smartphone available?

If you also currently have a VPN enabled on your phone, disable that which can get in the way.

@Bdubs I had the exact same issue - the switch lost its connection, I couldn't control it via the phone, etc. It would not connect to the phone when I tried to pair it from scratch. I found that I had to go into my iOS Settings, scroll down to Kasa, and enable "Local Network". After that, I was able to go through the setup procedures to set up the switch.

@BEtter thanks, but it turns out I was able to fix the issue by resetting my WiFi.  My guess is that there was an IP conflict and resetting my router reassigned all the local ips correctly.
