I’m new to Poly and Glider and have the same issue with an incorrect song count. In the Poly sits a 400GB microSD, loaded with 9184 songs as counted and indexed by Gofigure, most of them high-res and all of them are ALAC files, all equally metadataed in iTunes, manually copied onto the microSD from my Macbook Pro.
Glider only counts 4.6k songs and thus merely plays half of my music.
I have re-indexed the microSD several times using Gofigure and have re-synced in Glider at least 10 times. I have deleted and re-installed Glider on my iPhone ca. 5 times but all to no avail.
Any new insights or solutions since April? Your advice would be much appreciated!
