When I updated from an iPhone 12 Pro to an iPhone 14 Pro* a few months ago, something apparently went wrong and the connection (aka “Visual Voicemail”) to the voice mailbox with the carrier broke. One of my contacts asked whether I had received their voicemail — I hadn’t and surprise, when I manually dialed in to the voicemail, I had 17 new messages. That sucked, because there were obviously some important messages among them.
