### EDIT: Determined that animated Video type notifications are in fact working, as my initial test video was too short. GIF type notifications are the issue here. Thread title was updated to reflect this change.

I've been trying to setup an automation that sends a notification to an android device with an animated GIF or Video attachment using the _Send Notfication via Mobile App_ method. When sent, both the GIF and MP4 formats of a file will only show the first frame, instead of playing as an animated GIF in the notification shade. Through my reading, it seems the animated GIF support is very new as of Android 14, but the video support should be well established. I've attempted to follow the [Standard Attachments](https://companion.home-assistant.io/docs/notifications/notification-attachments) docs closely, and my configuration (of the GIF version) can be seen below. The video version simply replaces _image:_ with _video:_ and the _.gif_ with _.mp4_ extension (I have both files stored locally):

```
action: notify.mobile_app_s24_tugg
metadata: {}
data:
message: You've achieved your weekly eating goals! Great Job!
title: Nutrivore
data:
notification_icon: mdi:party-popper
color: "#8A2BE2"
channel: Nutrivore
importance: high
image: /media/local/spongebob-dancing.gif
clickAction: /lovelace/nutrivore
enabled: true
```

I've tried stripping this down to the bare essentials (removing channel, notification_icon, clickAction, ect) with no luck. I also tried using the web URL of the GIF source without success. The GIF and the video both correctly play from the "Media Player" folder in the Home Assistant frontend, so I feel the file and it's format are "correct" here. It feels like the companion app isn't even attempting to play the media, instead falling back to a thumbnail or static configuration, but I'm just guessing here.
