Voice-Mail Delay On iPhone 12 Pro
I received two "Missed Calls" from my Doctor's office but no voice-mail.
One was on Tuesday, the second on Thursday.
It was very urgent and important that I get test results, but there were no messages.
The following Monday, seven days after the first call, 2 voice-mails show up on my phone.
They were connected to each call, but didn't show up until several days later.
Before you suggest every typical solution, Yes I update the phone software,
and I restart the phone every few days, and checked the settings. It should be in perfect working order.
