I can’t rename or add a photo to a playlist

It’s an ok app, but coming from Spotify I realized that Google Play Music doesn’t even let you rename or add a cover image to a playlist. If you want a new name for your playlist, YOU HAVE TO DELETE IT AND MAKE A NEW ONE. WHY?! It’s so simple please let us rename playlists and add cover art. Oh and also make the app faster. It gets slow after a while and heats up me iPhone 7 Plus. Why tho?
