Yeezio Video Music Player funktioniert nicht

Yeezio metronome is very suitable for beginners, they can learn various musical instruments, such as guitar, piano, ukulele, violin, etc. 1.  It's really easily to use, you can select the time signature first, then set BPM you want and tap the start button.  Music in your Onedrive will be downloaded to the page "Music" and page "Video".  Just tap the "Stop Button" to stop metronome any time.  After getting your authorization, you can manage your Onedrive through Yeezio. 3.  You can click "+", "-" or rotate the button to set the bmp you want.  Log in with your Onedrive user name and password. 2.  Please contact me if you have any problem: yeezio@qq.
