Why does Dropbox always give a little, but takes so much back with each update? I use Dropbox to share music with collaborators - I'd prefer not to, but they want to use Dropbox. The latest upgrade now has an embedded player, and it's now easier to share files - so finally after years of the Dropbox app telling me there was no way to open an MP3 file, now there is - but the player can't be backgrounded - how utterly annoying. You need to keep the screen alive to listen to the MP3. There is an option to open the file in Youtube Music - with apparently the option to 'always use this app' - but typical Dropbox, that doesn't work. I'm really unimpressed, this would seem like an obvious feature, you basically can't use your phone for anything else while you are listening to a sound file. Lame. Really lame. Two begrudging stars for actually allowing me to listen to a shared file after all these years.
