STHM Responses

@jkp, I had that same STHM SMS Response saving issue back in February.

However, I was able to resolve it myself at the time. I uninstalled the latest version of the SmartThings Android app, and side-loaded the previous version at the time which was SmartThings version 1.7.40-21 for Android. The older version allowed the contacts I entered into the STHM Response feature to save. I even updated back to the latest version of the SmartThings app at the time, and my contacts were still showing in the Response section of the STHM.
