Hi, opened a new thread since this will otherwise get lost in the mega FiiO M11 thread. Es geht um das leidige Thema der nicht funktionierenden Amazon App auf dem FiiO M11. Have the same issues! Have tried some of the same steps with no result. @FiiO I have my FiiO M11 and my Samsung A8 (2018) side by sie. On the FiiO M11 only wheel spinning on the Samsung A8 direct play back. I agree with you. This is fascinating. I downloaded whole playlists and I still get the circling play/pause button. It also does not work independent if the playlist or songs are HD or Ultra HD. Do not know if this is helpful. On my FiiO M11 also on Qobuz when I start my first song of a playlist which is completely downloaded (CD quality) it takes incredible long to start. Often like 30 seconds. This is not the case with the FiiO M9 or any other device. Other thought my FiiO M11 is not shown in the device list of my amazon music settings. Might this be the reason? Okay, I tried all ways described here but with no positive outcome. It makes no sense for me at all that Qobuz on the FiiO M11 also needs most of the time a minute to start playing (it did not on the FiiO M9, it does not on the Sony NW-ZX2 and it does not on my iPhone, iPad or Samsung A8! And in addition the amazon app does not working in anyway. Please @FiiO sort it out with Amazon. Thank you.
