Issue Summary

While it is possible to edit files with Companion, save and then it is uploaded the new version on Confluence, when we go back to the page, when checking the attachment on the page, it shows a "Failed to Load", instead of the preview.

Steps to Reproduce

1. Create a page
2. Upload an attachment in the page, eg: .doc .docx, .xls or .rtf
3. Make sure the Companion App is open
4. Go to the attachments page and click on Edit on the attachment uploaded
5. Edit it with the companion app > editor (Office word or text file for example)
6. Make the edit and hit save
7. Upload the new version edit by clicking on Upload in the companion dialogue
8. Clicking on the ">" button to show the attachments versions, you will see a new version was uploaded
9. Go back to the page to see the changes

Expected Results

The preview for the file is available and the changes on the version were applied.

Actual Results

Failed to load is shown on the attachment

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
