Is it possible to hover over a building to see how many hours product is ready on a phone.
Before production is ready it's possible but I hear for computer users also when product is ready.
As far as I know there isn't a mouse-over hover equivalent on mobile. You have to tap the building which then collects whatever is ready whether you want to collect or not.
It's a challenge when you have a string of the same buildings with different productions all ready for collection. Got to rely on memory of what productions you started where
