Export on iOS

[1-user1]

I can't export any stops/gyms on iOS. Both, using "Save..." and "Export Gyms & Pokestops" result in a file (it seems to be the json file), which can not be saved. Tring to save in iOS's defaults files app immediately closes the window. Tring to save in a ownCloud results in the error "Cannot load representation of type public.file-url".
