There have been some problems with text messages since the outage. It should return normally.
However you should check your notification sounds just in case...
@Bigjannie Check your sound settings to see if your Do Not Disturb is set to come on at a specific time. If it is, you can turn that action off.
Hi @Bigjannie, it's been a few days since you posted your question around the text notification sounds, so I just wanted to check if things have returned back to normal now with them, or if you're still experiencing the issue?
