Hey there @pablo_cba,
Thanks for reaching out - we’re here to help!
Hope you don't mind us replying in English as it's the Community's official language.
Just to confirm, have you tried a clean reinstall of the Spotify app on your device? We recommend this step as it'll remove the old drivers first and then install the new ones. This tends to solve issues with the app's performance.
Give your device a quick restart as well before you open the newly installed app.
Make sure you disable any power saving or data cleaning settings on your mobile device. Alternatively, you can try authorizing Spotify to run without restrictions despite the mentioned settings being enabled. It’s worth it trying this since such features can often prevent the app from operating at full capacity.
Hope this helps. Keep us posted.
