Phone App - Frustrating

I finally got to purchasing a mobile phone for myself. One of the first things I wanted to do is use the Sonos app with my android phone. Until now, I’ve been using the app on my computer for years. First off, the phone will not load the playlist on my external drive into the queue. Never been a problem with the computer app. It gives me the informative message “Unable to add to queue”. No matter what I do, it will not create a queue from my playlist - very disappointing. Second, why in comparison is the computer app so straightforward and easy to navigate while the phone app is very confusing and frustrating? I was going to purchase a Move for my wife, but she will never be able to navigate that convoluted set up. The computer applications is so simple and practical - why complicate it?
