Can't add my own sound/music to Premiere Rush on iPhone anymore

Hi, a few days ago it seems like Premiere Rush did an update on my phone, and I can no longer add my own sounds anymore. This is importnat because I'm a music producer and the entire reason I got Adobe was to do this, it looks like I'm only able to now add stock sounds and songs that adobe choses. 

Can someone please give me clarity on this? If I'm unable to add my own music from the files section of my iPhone or even from emails it would be quite dissapointing and frustrating. 

Thanks so much
