Hello,
I have used do not disturb for years and when it became focus I went into focus and chose to turn on do not disturb and I have my husband added as a favorite so he can still reach me even when do not disturb is on. I had no problem with this until recently. In the last two months I am no longer receiving phone calls or notifications of missed calls. The calls are sent to voicemail and the voicemail says it’s full which it is not. I have gone in and reset network settings multiple times and it just keeps happening. I am missing important phone calls and I am not receiving voicemail messages as well as no notifications of missed calls or voicemails. I hope you can help me.
