Here you can find a download to the X series version of FiiO music app, currently at 1.1.6 https://www.fiio.com/newsinfo/342482.html.
Just put on internal storage and install the apk over existing installation.
There was a 1.1.7 apk that I saw floating around 4PDA but I cannot find an official page or press release (in English) for this version. Searching for it is difficult because FiiO music versions are basically drowned out in search results with firmware versions (1.1.7)
Thank You for the help, Able to install the 1.1.6 version in my player - Thank You
Fiio must maintain an FTP type directory for the app for older players.
