For years, my app has been receiving XLSX files from other apps using the share command.
For example, in an email, I use the share command on an xlsx attachment and send it to my app.
From my app, I go to the Documents/Inbox folder and find the file.
This mechanism has broken! And I'm not talking about an app compiled with XCode26, but simply installing my app, still compiled with XCode16, on iPadOS26.
It seems that the operating system no longer puts files in the Inbox. Is this true?
