with the last update for android does not appear the option to choose the place of the storage of downloaded music (internal or SD card)
Hey @Icamposalarcon, welcome to our Spotify Community!
To start, can you let us know what device, operating system, and version of Spotify you're using?
Also, does the SD card have at least 1GB of free space? Last but not least, can you head to Settings > Apps > Spotify > Permissions >, and give Spotify "Storage" permission?
Let us know how it goes.
