SAP BI App on IPAD showing Stacked Bar Chart as Group Bar Chart

Hi,

We are having issue with showing STACKED Bar chart on BI APp 6.1.9 on IPAD. it was all good but couple days back we notcied that Stacked bar chart is shown as Group Bar Chart. We had checked WEBI and no issues with it, correct bar chart is show in BI Launchpad.

We are thinking is it because of update to BI App . Not sure

Please help

Thanks & regards
