When you have a large bill and want to split it, it wont work. If you press split it does nothing, but buggs out printing and the entire app. Only restarting the app will help.
I still do not get the point, if you have a large list of positions, splitting works fine on my test devices. Or are you referring to another issue?
What do you mean with buggs out printing? Splitting does allow you to mark a subset of positions that you can checkout then. Afterwards you can either checkout the rest into another invoice or do the splitting again.
