Your later rants were that your iDevices SiNCE your daughter ended up updating these are not functioning as they should.
BTW, I DO the same as you.
I wait out iOS upgrades/updates for, at least, a week, sometimes a lot longer, if there are reported bugs/issues.
Unfortunately, I couldn't wait as long as I would've like to to update to iOS 9.3.1 because there is a fairly major security threat of a remote activated version of the iOS date/time bug that can both brick and burn up your iDevice's internals remotely over a public, open WIfi network.
This had been discovered, just recently, and this vulnerability was specifically targetted to any iDevice still running the older iOS 9.2.1 update.
So, I was, sort of forced, to update my devices, just under a week, because I have two, relatively, brand new andvexpensive iDevices, that I do not to get wasted. And I have two older iDevices that I don't want trashed, either.
Anyhoo...
Your iDevices are pretty new. I would strongly suggest you get your yourself and your iPhone and iPad to an Apple Store to get them to fix your iDevices and get them back to working properly and quit all of B.S. that you keep posting here about it!
You do not have to update your devices after this and there is a way to get rid of the update/upgrade notices for awhile ( Settings App, General, Storage and iCloud Usage, Manage Local Storage. A list of apps generate. The iOS upgrade/update file appears within this list where you can tap on it and delete the upgrade/update file for awhile. The red balloon notification will not dissappear, but the actual update file will be gone from your iDevices.
The upgrade/update file will return, but much less frequently and you can still remove/delete it the same way each time.).
This is how I put off iOS upgrades/updates for awhile without the update constantly bugging me to install a new iOS upgrade/update.
In the meantime you can get Apple employees at an Apple Store to straighten out your iDevices.
You want your devices to go back to working the way they were or not or keep coming here ranting about all of your issues and complaints with Apple doing this and that.
From here on out, you now know how you can keep iOS upgrades/updates off of your iDevices for as long as you want.
