Error UI-REL-001 Large idx in Selectors Target > Strict selector from activity Select Item ‘Paid on’ contains large IDX number. Threshold is 4 Main.xaml
Recommendation
The idx attribute is used to distinguish elements with the same selector based on their order in the interface hierarchy. This order can change if the elements on the screen change, so the value for the idx attribute should be kept to a low value to avoid the selection of wrong elements.
Consider using other attributes in the selector to make it less dependent on the idx attribute. Learn more.
You shouldn’t be using idx in selectors at all. You need to modify the selector to eliminate the need for the idx.
Try using other attributes instead. IDX tends to change every run. Can you paste all the attributes that are available in UiExplorer?
