.db fail

Perhaps it’s just a problem with my account? However I went through a lot of work adding songs to play lists and my online library and they do not appear to transfer between devices. It’s on THEIR servers, it’s a simple .db to maintain and their other services such as YouTube and YouTube Music maintain that data. Furthermore my account seems to allow more than one device to play at a time, which it’s not supposed to. Therefore due to transferring devices and the issues I’ve experienced I can no longer give this app the four stars that I would have a week ago (it has legitimate caching problems as well when streaming) , and must give it a single star because of lack of portability and not working as advertised.
