My text msg won't make a sound anymore when closed

[AC Question]

Ever since the latest system upgrade on my galaxy s7, I no longer am notified of text msg or email even when it's closed. I reset functions numerous times and nothing. Also, autocorrect is horrible. It corrects common words incorrectly forcing me to correct them three times.
