I search for an artist. I tap the artist in the search results. I scroll down and tap to view all of their albums. I chose one, tap into it, and tap the first track to start listening to it. When the album is over, I open Spotify again and tap the back arrow, expecting to go back to the album list. Instead, I'm back in the search results for the artist... 2 taps and some scrolling further back than I wanted.
I think this is a bug or a poor UX decision. There is no need to go back to the search interface, assuming I want to listen to a different artist, when there's even a search button on the bottom toolbar. Please make sure back goes back only one step in the search/browser history.
This sounds more like an issue that's worth investigating. Could you please search for that issue in the respective help section and provide more info about the issue. If it doesn't exist you can create a new topic and let us know about it! Then we can check it out there.
