What went wrong?

Ive had google play for about 2 years now. At first it wasnt all that but they fixed many issues with the app and it worked perfectly, so Ive kept it. Ever since their latest update with the icons being at the bottom, the app has NOT been able to work properly! Some of my downloaded albums will not play. Downloaded playlists wont play either, some songs will play some wont, or itll skips song. Then trying to play new songs takes forever to actually stream. Its way too much buffering. Hope they get this fixed soon, until then Ill have to stick to Spotify or Apple Music.
