Problem #1

I try to make Pivot Chart report for one of my app, when press button Create page start loading but after long time waiting still not load. Other type of reports can make without any problem for this app, just Pivot Chart not working. For other app Pivot Chart reports working well.

Problem #2

In Report type List can make several criteria and all must have or logical "AND" or logical "OR", can't make complex criteria. Before have group for this, now can't find it. Is it possible to make complex criteria with different logical types?
