Googling this question gives a wide variety of results but I don't see anyone actually asking or answering it so…wtf?
Long press, nothing but share, delete, archive, or add to album. No sync, download or anything of the sort. Is immich supposing it's a one-way trip? What if I want a photo I backed up a year ago, I have to open the webui?
No one is asking the question because the option is there.
I'm Immich, find a file that has an empty cloud icon (indicates a file on the server and not on your phone). The top bar shows 4 icons: heart, cloud with a down arrow inside it, plus sign, and info circle.
Click the cloud with the down arrow inside it to sync to your device.
Alternatively, the bottom bar also has your OS share button which offers another multitude of ways to download and send the photo.
omg hi immich I'm such a huge fan
So nice to see Immich here! Your work is amazing I love it
Ahhh see I had everything backed up already. Shit. I should've tried it after deleting something. I figured it would find a button and be asked where I wanted to put the file. Share kinda works for that.
