Can not seen reports in IPAD

Hi Experts,

We are on BO 4.0 SP 6

I am using BO Mobile Reports, all of the sudden, i don't see my Mobile reports under user IPad's.

When i see in server, those reports are there under Mobile category, but ! why don't they show up on IPads. I have restarted the SIA and tomcat, but still no luck.  I am able login to SAP BI Application, but "No documents available" message under server All option, where as my BO Explorer is working fine.

I have check the authorization, even i tried to login as Administrator user in IPad, still no use.

Kindly advice.

Regards,

Suresh
