S9plus help...please

[donnajay]

I found that messaging notification sounds are gone...sucks. I have 2 questions...
1. Why is all my text messages coming thru as messenger?

2. I cannot assign a ringtone to a contact. When I choose a ringtone, even a default one it wants me to tell them what app to get it from...

So far so good...I'm coming from a s6...

Thanks
Donna
