I do not know if anyone else is getting this, but my 5s is now taken another step in trying to get me to download 11.3. If I try to check my phone, I now get a message that asks me to input my passcode (as opposed to my fingerprint) to download OS 11.3 TONIGHT if the phone is plugged into a power source. It is getting harder and harder to bypass these prompts. I am afraid to go to sleep without powering off the phone entirely. I am getting the message on my Mac, too. I have to keep telling it "remind me tomorrow." I cannot find an option to make it stop reminding me. Dear Apple, if you are reading this post, please know that I do NOT want OS 11.3 at this time. Please STOP trying to force me to accept it! I will download it whence I feel comfortable about it and NOT before.
