I have Smartthings set up to turn on my lights by proximity of my phone. Yes, I have location services on. It works okay when I get home at my normal time but if I come home early, my lights do not come on until it is about the normal time for me to arrive. I do not have anything scheduled to turn them on at a particular time, just by proximity, so this makes no sense.
I’m sure that’s very frustrating! 
Which app are you using, classic or connect? And can you show us the screenshots of the automation that is supposed to turn the lights on
I guess I was using Classic. I never really open it and didn’t know it was changing, so I got a popup about it. I did the upgrade and it came up with a big circle saying “SUCCESS” and then another popup opened and said that it failed, so I’m not sure which one I’m using now. It looks the same.
I screen shot three screens in the automation:
My automation needs are quite simple so it’s annoying when this doesn’t work.
