Hi @Gevian , thank you for reporting this problem. When the downloads you describe fail, is there any error message? If so, could you please include it here?

The message center states (in german):
"Herunterladen fehlgeschlagen. Herunterladen von xxx.pdf konnte nicht abgeschlossen werden"

Important:
When I use FolderSync.App or the Synchronize Ultimate.app on this mobile phone - syncing works perfectly!
