the background refresh takes entirely too long, I have to turn off the automatic update library then turn it back on in order for the app to recognize newly added files. Secondly, a lot of the files which are properly tagged are not showing up under "albums" and are not downloading the album artwork which is a big issue for me. Definitely needs to be fixed. Those are the only two things that are deal breakers for me, Ima still use this app but it blows my life that the album art doesnt show and refresh rate is trash.
