Posting to Tumblr used to be easy and sharing from the spotify app directly to tumblr would create a post with a legible and user friendly box with the song title and album art and whatnot and now when i share to tumblr after my app updated, it just posts a hyperlink/the URL for the song and its not good for sharing at all ☹ i see other people on tumblr still sharing songs showing up as the track box... please and thank you in advance for any advice or help
(android 7.1) I had that problem after flashing a stock rom. what I did was to goto app settings in android. I force stopped then cleared the cache, rebooted and it worked again. hope that fixes yours too.
