While I was trying to make the cover larger, it suddenly disappeared and there is no way it to make it appear back. I haven't tried restarting/uninstalling because I don't want to lose settings and it's annoying. Is there any other way to recover the song covers back visible?
It didn't work unfortunately the way you said, however, I simply re-installed it but I lost all my settings and now I got to setup it again! Whatever, it showed back after reinstalling. Thank you anyway!
