Can't managing Sinope thermostats with new Smartthing App

The recent migration to the new Smarthings app have snowballed into a few major issues with my Sinope thermostats (TH1124ZB and TH1123ZB).

It appears that I can’t change the Thermostat Mode from “Off” to “Heat” from within the app, rendering the thermostat useless at the moment.

Curious if anyone has similar issue, and if there is a work around, perhaps pushing a change to the device through the IDE.

It doesn’t appear I’m able to change the mode physically off the thermostat.

Any help would be grateful! It’s getting cold here :cold_face:
