Exact same issue as Ryan (from 3/22/22). The app says it can't connect to my Lyric Thermostat, then 1-5 min later it reconnects. The Thermostat itself never shows as being disconnected from my internet. Happens every few hours. Have spent 45m with Resideo CS on 2 separate occasions with no remedy. Their only solution: "call your ISP". Obviously not an ISP issue, as no other wifi device has any issues!!
