Subject of the issue

Unable to download attachment after uploading via Android app. Downloading after uploading via web vault causes no issues.

Deployment environment

vaultwarden version:
v1.25.1

Install method:
Docker image on Synology NAS
Clients used:
Web vault, Android app
Reverse proxy and version:
MySQL/MariaDB or PostgreSQL version:
SQLite
Other relevant details:

Steps to reproduce

Upload an attachment (to personal item or organisation) via Android app.
Try to download on Android app afterwards: "Cannot download file".
Sync with server.
Try to download in webvault.
Popup shows correct name and size of attachment.
Download attachment: 1kb file regardsless.
The attached file does show up on the server in data/attachments/[FOLDER] with an expected size.

Expected behaviour

Uploading an attachment via the Android app should allow you to download the attachment later from any client.

Actual behaviour

The attachment is "gone" after uploading it via the Android app, cannot be downloaded and can only be removed.
