@youtubemusic I absolutely hate it, I can't search my own library that I imported, cannot start a radio mix based on my own library. If I do start a radio, and I use ytm in the background the music stops. This is so inferior to Google play music.
Sorry to hear that – once the music transfer is complete, try to reboot your device. Your stations from GPM are now playlists on YouTube Music (which is on the Libary tab). If the issues persist, you can reach out to our live support team here: http://yt.be/help/9aqk
