PC used to be the optimal UI for Spotify (across seemingly infinite different UI designs for each platform) but this new May 2021 update is a big step backwards. The UX is terrible to have every single platform have an utterly different UI from the others.
New search bar requires 2 clicks to access. You can no longer toggle the list vs. album sorting methods without first digging into a sub-category (Popular, Albums, Singles) so there is no way to see a list of all of their songs at once.
While I'm at it...why can I swipe to add-to-queue on iOS but not Android?! What a simple quality of life improvement, especially while driving, that is simply not present on any other platform.
