Original GitHub issue: https://github.com/binwiederhier/ntfy/issues/529

In the case below, the attachment can only be downloaded from the notification action button, but not from the ntfy detail view.

curl -d "Here's a notification with an .apk attachment" -H "Attach: https://f-droid.org/repo/com.calcitem.sanmill_3178.apk" -H p:4 ntfy.sh/demogoogle

Here's a video+screenshot showing the issue. The first attempt in the video works, the following attempts do not: https://photos.app.goo.gl/mKAEyh7VYyWBmtaW6
