Still no go – Flacbox: Hi-Res Music Player Review

I keep coming back to this hoping to shake it loose, but still no success. No matter what set up I cannot connect to my music via the iTunes library, though signed in to Google Drive it won't "connect", Dropbox, etc… it most certainly could be operator error, but when the most recent support document I can find for an issue is 2017 and a few versions back, well…
