iOS：将文件从 Office 应用复制到我的应用文档

Question

I'm not sure if this is a programming issue, but hopefully somebody can help me out anyway. On my iPhone (iOS 13.3) I'm trying to copy a file from OneDrive into my app's document folder using the Files app. I already set the keys UIFileSharingEnabled and LSSupportsOpeningDocumentsInPlace in the info.plist file so my app appears eg in the iTunes FileSharing section. It also appears as a possible target when I share a picture from the "Photos" app or if the source in "Files" is a standard app. But whenever the source is an MS Office app (OneDrive / Excel / Word / ...), the target app list is reduced to Office apps. No other app - neither mine nor standard apps like "Pages" or "Numbers" - appears in the list.

Does my app need a special setting to retrieve OneDrive files, or is this a more general Office issue?

Answer 1

Obviously this is caused by a restriction defined by my company's IT department. Sorry to bother you.
