[Help] i could not export the network i build on my packet tracer on my iPad. The file is saved on iPad packet tracer app but I can’t export it via Dropbox or email although the options are available inside and they are not working.

I build my network in packet tracer in my iPad and after the completion I tried to save it its saved inside the packet tracer saved file but when I tried to export it or save it to drop box (.pkt) file its not saved in my Dropbox ani I tried to forward it as email it says no email address is assigned. I have my assignment submission due on 3 hours from now. In serious trouble. Can anyone help ?? I can’t export the file and submit it. It’s stuck inside in my iPad packet tracer app
