I have a Collection view that needs to change a value called selectedQuantity.
This collectionview is in a Popup.
When I Tap on a number for select the quantity, the itemselected not change of color. But If I press the Save button, the quantity is saved perfectly…
I need to press two times de same number to see how the background of the selected number changes.
I dont have any style that needs two taps… Can anyone telle me why happen this?
