Yes,
I'm able to logon with SAP Mobile App and list documents, but the refresh fails (in fact I checked that documents refresh right with BI Launchpad!)
The error is generic, without code, issued in italian is:
"Impossibile eseguire l'operazione"
translated in english it sounds like: "Impossible execute the operation" or "Unable to execute document"
it's a dialog box without choices, only a "OK" push button
