Yes! Found that others having same issue. Before it was enough to restart phone to trigger media scan. Maybe it changed in Oreo. Resilio sync is not issuing media scan when syncing music, photos, etc. Resilio, please implement media scanner after adding files http://www.tatnorix.in/how-to-run-media-scanner-in-android/ For workaround move the files to ".nomedia folder" and back to music folder. Or clear Media Storage cache from application setting. If there is a another way, please let us know!!!
