Since the big update, I am not able to see who sent me some music. I just see the personal number in front of the optional message but no name. So I have to get to my desktop to double check the sender's name. Is it just because my inbox is hudge an filled up?
The inbox tab on iOS shows Spotify usernames for everyone for me too, which includes numbers for people who have Facebook created accounts. Hopefully we will get something similar to the message tab on the desktop Spotify on the mobile apps which will fix this.
