Dont block users (i.e. make them wait) when saving the current 'card'
When one clicks a 'save' button after entering the expenses, the app syncs the data from the server not in the background but allows the user to wait for the card to disappear, which might take a dozen of seconds to happen on a slow internet connection. I think you might have figured out by now that what needs to be done ;)
Thanks for the suggestion! This definitely makes sense, though I know there are also some technical concerns (such as what to do when saving the expense returns an error). Still, hopefully something we can add in a future update :)
