Ok at least it's not just me then, must be iOS 10. I can't remember if it stayed beforehand but if you say did then it's a bug presume.I have wondered this as well. My area does not have 3D in Maps, so default view ("Map") does not have place settings for houses and buildings. It used to stick on last setting.
Oh no. Any Apple stores near could use that?My phone is stuck on boot screen after something with 10.1 and/or deleting Facebook (but 130mb of Facebook kept showing back up under storage), and my Mac is too old for Apple to allow current Itunes to restore iOS 10 while iOS 9 is too old for Apple to approve and let iTunes use it to restore.
Once I find a neighbor or somewhere other than Apple to restore iOS and then after I set it back up it I will check.
