Why are my voice mails not being saved since iOS 10 upgrade?

[iMore Question]

Since upgrade, I can see I have a voice mail, but it doesn't show when I try to retrieve it.

What do you mean it doesn't show? Does it not show the transcription or you're not able to see who left a voicemail & listen to it? Sometimes rebooting your device fixes these quirks.
