My wife has an S20 on Android 11 through T-Mobile. She's not getting any voicemail notifications. I checked and all notifications for it are turned on. I did a test call myself and left a message but nothing.
I can see a notification of a missed call. Calling the voicemail, the message is there.
I don't have Samsung anymore so not sure what I'm missing with the latest version.
Anyone else having the same issue?
