@bosco : I followed your instructions and I now have a copy of dropbox 11.7.0 in site-package-3. How do I import the newer version into my Skript rather than dropbox 6.4.0?

Have you been able to solve this issue in the meantime? I'm having the same problem on an IPhone 12 pro iOS 15.3.1. Used to work on my IPad.

@cvp : this line did the change with the example code as well as with my application.
Thanks a lot

After some search in this forum I get to the conclusion that my issue might be a new one.
I did a vocabulary trainer with an ui.view to display labels and buttons of some kind.
One of these buttons calls an ui.list_dialog, where I can choose from a list of strings. The dialogue used to block the underlying view, so I could retrieve the selected string in the following line of code.
After updating my IPhone to IOS15.2.1 this is no longer true.
This is a very short code to demonstrate my problem

# coding: utf-8

import dialogs
import ui


class my_view(ui.View):

    def __init__(self):
        self.background_color='#ffffff'
        btn = ui.Button(title='Okay',action=self.action)
        self.add_subview(btn)
        self.lbl=ui.Label(text='None')
        self.lbl.y=btn.y+20
        self.add_subview(self.lbl)
        
    def action(self,sender):
        act=dialogs.list_dialog('select',['A','B'])
        #next line is executing before dialogue closed
                 self.lbl.text= act
            
if __name__ == '__main__':
    v = my_view()
    v.present('full_screen') ```
