Schlage Century status "unknown"...and I'm away from home

My schlage lock has been working Ok for the couple weeks I’ve had it. Just today I came home and it didn’t unlock as part of the I’m Home command as it should. I left and noticed sometime later that the lock command was sent and the lock status sent back “unknown”. When I hit the button, it says “locking” for a while and then reverts back to unknown. I’ll be away from home for a couple days and I’m guessing my door is unlocked. Any ideas on what I can do? My confidence in smartthings for security purposes is rolling downhill. This really isn’t acceptable if ST is going to be marketed for things like this.
