unable to assign RT to contacts

Question

I have had my Galaxy S7 Edge for 2 days and have been trying to get certain ringtones assigned to certain contacts and it just will not do it.  below are the steps I take to assign:

1 - click on contact

2 - click edit

3 - click Google @ top of screen ( since i use it as contact backup)

4 - click on default ringtone

5 - song i want is not listed so i click on 'add from device storage'

6 - it sends me to Verizon cloud

7 - click on the song i want

8 - click save after seeing the song is listed

9 - redisplay contact; Ringtone shows as Default Ringtone instead of the song I chose

Called Samsung; they had me do a factory reset (which I hate); did not fix the problem & now I have to reset the phone back all over again to the way I customized it. She told me go to a Best Buy and speak to a Samsung rep in person. Not sure why; should she not be able to do the same to fix the issue? Can anyone advise what's going on and how to assign? Thanks.

Thanks Deloused, I finally figured it out. When I was setting my phone back up after the reset, I downloaded a music app. When I tried to assign RT this time,  it gave me an option to use Cloud or the Music App; chose the music app. I didn't get that option the first time around because I had not DL a music app @ the time. Now everything works smoothly. I just assumed this fone came w/ a stock music app.
