Other user can see my (admin) photos when they log in

I saw another user on Reddit asking about the same observation, but don't see that he brought the issue here. I set up Immich on Ugreen Nas 6800 today and uploaded 18,000 of my own photos through the Android app as the Admin user. I then logged on with the account I made for my wife (non-admin) and she can see my entire library and folder structure. I tried clearing cache on my Android device and then clearing all data and when I log in again it's the same, we're looking at the same contents. On my server she has a separate folder that's populated with some of the same folders as my library - it feels like there was some persistence in the Android app between logins that then "infected" the other user library? Partner sharing is not on.
