The bug

Hi,
when I share an album with my partner and she tries to save single photos from that album to her iOS gallery app, the photos won't show up in the app. As we are german the translations to english for the button are my assumption. In brackets I put the exact german Text for the button.
What I tried:
Use the "Share" (Teilen) button -> iOS Menu opens with "Save Picture" (Bild sichern) button -> press this button
What I expected:
The image shows up in the gallery (Fotos) app (native iOS photos app)
What happend:
Photo didn't show up in the gallery app

What works:
Download the file via 3-dot menu -> "Download" (Herunterladen) -> Photo shows up in the gallery app.

The download button is the intended way to do what you're looking for. I have no idea what the idea behind the "save" button in the share sheet is, but at that point Immich has already handed the file off to iOS and I don't think there's anything we can do to affect that behaviour.
