Spotify excerpts bug

Hello, I've had an iPhone 12 for about two weeks (it's new so that's not where the bug comes from) and I had a playlist in the Spotify app that was working perfectly. But since today, the display mode of my playlist is different: I only see the titles of my songs listed one after the other, without images. When I click on it, a widget appears with all the titles of my playlist displayed normally, with the images and in order. I click on it, and it only plays a snippet of the song instead of playing it in full. So I click on the "play" button that normally allows me to listen to my playlist in its entirety. Indeed, the music starts playing, but randomly; it's not at all in the intended order, I can no longer skip, so I can't change the song: a widget appears to tell me that it's a premium feature.
So I leave the playlist and look for songs in the search bar; same scenario, impossible to click on it or listen to the music in full. Spotify is therefore unusable.
Thank you in advance for your responses!
