iPhone XR silencing daytime calls
iPhone XR iOS 17.3.1
I HAVE BEEN USING FOCUS BEDTIME, AND SET DND FOR BASIC GRAVEYARD SHIFT HOURS, 11-7 adjusting slightly occasionally. My iPhone has been silencing calls and sending them direct to voicemail routinely during the day. I have missed calls from my eye doctor with needed information prior to cataract surgery, and from the pharmacy regarding medication I need to take beforehand. There's no good explanation for this I know of, and the simplest thing for me to do right now would be simply turn off do not disturb- but that's not an option.
Focus/sleep/bedtime is causing me much more trouble than it is worth, and it's serious.
If this is not a bug, please tell me the simple fix. Thank you.
