Spotify unable to edit playlists and other minor bugs

With Spotify’s latest update, can no longer reorder songs in playlists: next to each song, there used to be a Reorder button, which via flicking up/down, the desired song would be reordered within the desired spot within the playlist. Either Spotify did away with the Reorder function, or it’s a voiceover bug, in which the Reorder button isn’t seen.
Also the bug of when adding music to a playlist, it won't add it at the end as default, rather in the middle of the playlist!
So in talking to a blind friend with Spotify, and when he told me he didn't present any of the bugs previously-mentioned, I uninstalled, restarted the phone, reinstalled Spotify, and all is well! So just to make you'll aware if you have these bugs, don't think Spotify is screwed up. Also the above-described procedure went even better than expected: the size of the Spotify app came down from 1.2GB to only 206MB! Wow! So I guess I killed2 birds with one stone?
