Blank report in ipad

Hi,

I cannot view my report in ipad. On my ipad, I run sap b1 -> login with my initial -> go to reports -> and select the report i want to view but it is blank, just a white page. I try to put in a simple report with just the text "Testing" also nothing appear. I confirm i able to run the report in B1.

I switch to demo and able to view the report on my ipad, so the problem is on integration framework.

I am on SAP B1 8.81 now and i able to view my report when i am on SAP B1 8.8.

Please help
