Issue Summary

If you upload an attachment using the new view, it may not be kept, or you may not be able to preview it.

Environment

Jira Cloud.

Steps to Reproduce

• From a board, attach a file;
• Close the issue, and get back to it;
• You will see that the attachment is not there anymore, but if you click to attach a file again, that same file will be in the recent uploads, but it will work properly now if you select it.

There are some different use cases for that problem:

• If you upload a new file, and click on Insert file without waiting for the progress bar/upload to be completed. In this one, the file will be gone after you get back to it: Docx quick insert file.mp4;
• If you upload a new file, and wait for the upload to be completed before clicking on Insert file: Docx file full upload waiting.mp4

Expected Results

The file should be available in the issue after you come back to it. And you should be able to preview it even after the upload.

Actual Results

You cannot preview the file after the upload, and the file will be gone from the issue after you come back to it.

Notes

I've replicated that behaviour with the following extensions so far:

• Docx;
• Xlsx.

The biggest part of the occasions where I've replicated it, was on Next-gen projects. It looks to happen way less often in Classic projects.

Also, most of the occasions are on the detail view from the board. But I did get to replicate it in full view in some rare occasions.

If you upload a file after an unsuccessful one, the file that was affected will be fixed: Next upload.mp4

If you do not removed that affected file before selecting it back from the recent uploads, you may end up with a duplicate: Cannot preview file.mp4

Usually, the file affected by such problem will have the following highlighted icon on it:

Workaround

Select the file from the recent uploads.

Uploading a new file will fix the affected file automatically (although the new one may be affected).
