Hello,
Welcome to our Microsoft Q&A platform!
If you used FilePicker
to open the file in iOS, actually it used UIDocumentPickerViewController
to achieve it like following thread. Doc limitation is "com.microsoft.word.doc","org.openxmlformats.wordprocessingml.document"
https://github.com/xamarin/Essentials/blob/main/Xamarin.Essentials/FilePicker/FilePicker.ios.cs
But all documents should present in your iCloud, Files and in Google Drive will be shown if Google Drive is connected in user device. Do you put your doc file in the public files or iCloud.
If still not work, you can try to create a dependenceService. Wirte native code like this thread:
Best Regards,
Leon Lu
