I've never set an Android device to update automatically, but would check periodically in the Play Store by listing my apps and seeing what I wanted to update. Today I went to do that on my phone and the My Apps option is no longer there. They've changed the interface, and as far as I can tell, there is no longer a way to get a list of my installed apps and see which ones have updates available. I hope that I'm wrong about that and someone can tell me where to find it on the new--and to me, diminished--Google Play Store.
