What do you do if an app is not working properly?

If a money making app installed on your smartphone or tablet is not working properly despite installing the latest updates , what do you do? Do you uninstall the app and re install the app or do you use some other method to fix the app?

I would try to update the app and most times, it works after this but if it still is not working, I would uninstall the app and find an alternative.
