The posted issue ocurs under Windows 10.
Now I’ve tried the procedure on an Android tablet and there I can manually identify the album.
If I try it automatical (without setting the album title), I’ll get a message, that I’ll not have a internet connection (which is not true).
But open again the windows client, the album will shown as not identified:
Now I’ve tried it a second time on the android device and now the behaviour is the same, like on the windows client → not be able to identify the album!
