My iPad notified me that it had downloaded the update iPadOS 13.6 some days ago. My iPhone still has no red badge or notification of an update though. If I look under General> software update it offers to download and install the update but it hasn't automatically downloaded it already. I figured that it just needed to be plugged in overnight for that to happen but several overnights later it still hasn't downloaded the update. Any ideas as to why not? It downloaded the previous update itself and notified me. I could of course download it manually, but would have thought I shouldn't need to do that?
