Why is voicemail blank despite there being messages unheard?
Since upgrade to iOS 17 voicemail is intermittently unavailable. The red dot indicating there are unheard messages appears and then disappears when the voicemail messages are not accessible. Turning phone off and back on doesn’t help. It also doesn’t help to turn live VM off and back on. Literally visual VM is unavailable and then randomly will return and disappear again. I have upgraded to the latest iOS on 10/4/23 without any help.
