Push notification icon shows as white circle when notification is expanded (collapsed state is fine)

Hi everyone,
I’m using the new native mobile push notifications (Send push notification workflow action, Firebase for Android).

Issue: When a notification arrives on Android, the app icon displays correctly in the collapsed state. But as soon as I expand the notification, the icon is replaced by a plain white circle.

What I’ve checked:

  • The app icon set in Settings > Mobile settings is a full-color PNG (no transparency).
  • I couldn’t find any separate field for a “small icon” (Android requires this to be a white silhouette on a transparent background — different from the large/app icon).

My hypothesis: Bubble might be reusing the single App icon field for both the small icon (status bar / expanded header) and the large icon (collapsed view). On Android, the small icon needs a transparent, monochrome white asset — if a full-color icon is used there, the system can’t render it and falls back to a blank circle.

Question: Is there a way to upload a dedicated small icon for Android push notifications, or is this a current limitation of the beta?

Thanks
