Unable to add Honeywell Lyric Thermostats to Smart Things



I had previously had my two Honeywell Lyric thermostats connected to my Smart Things setup. However, I noticed this morning that only one was now connected. I ran through the Honeywell Lyric Thermostat wizard, logged in successfully, Click Allow, and it saw both of my devices which I selected, and said that I successfully connected to Honeywell.

However, when I click next in the wizard to configure my thermostats, it loads a blank page. When I click done - it says “Error saving unnamed page. Please contact SmartApp developer.”

Any ideas?
