Sharing - Wrong sharing-status after editing file shared by another user [M]

Actions Performed

Preliminaries:
Another @xxx.xx user has shared an image file with you (NOT via link - but shared to you as a @xxxx.xx contact)
This file was shared with the permission to edit the file

1. Open the app under test
2. Go to the Files tab (DE: "Dateien")
3. Identify the file shared with you (see preliminaries)
4. Tap on the 3-dot-button next to the shared file
5. Tap "Edit image" (DE: "Bild bearbeiten")
6. Edit the file (use pencil, draw some lines etc.)
7. Save the changes - modal should appear: overwrite original file or make a copy?
8. Select the "overwrite original file" option on this modal (DE: "Original überschreiben")
9. Inspect the sharing-icon / status next to this file now
10. Tap the sharing-icon
11. Try to share this item (create link or share with Telekom contact)

Expected Result
Correct sharing-status. This file was shared by another user. Usually should have the status "Empfangen" (DE) and a cloud-icon with an arrow pointing upwards. This means that this file was shared with me by another user.

Actual Result
Incorrect sharing-status after editing a file shared with me + overwriting the original. The sharing status "Empfangen" (DE) and with the cloud-icon is not displayed. Instead of that, it appears as if this file is not shared at all. If I tap the sharing-button next to it, the sharing window appears. But if I make an attempt to share this file now, I get an error "404: The requested resource could not be found"

Reproduce the flow in the iOS app with an image shared by another user: edit it, overwrite the original, and inspect its sharing status and sharing action. Done means the file remains marked as received with the expected cloud icon and sharing it no longer produces a 404 error.
