That would be my guess--making a change caused the Dot to phone home to get the latest information off of the servers. I've noticed that when FW updates are released, my Echo usually updates days before the Dot. So maybe Dots are farther down the list of devices as far as when they get updates pushed to them. Even doing the trick where I put my Dot into update mode doesn't seem to make it download FW updates. I still have to wait until Amazon is ready to update it.
