My wife and I each take a lot of random photos and screenshots and things we don't want to share with each other (and we probably don't want to be bothered with each other's random stuff), so we don't want to just do something like turn on Partner Sharing on Google Photos.
You can specify what gets shared with partner sharing. My wife and I have partner sharing set up so that it automatically shares photos of our kids with each other but not anything else.
I thought about that, which is why I had so many failed attempts.
I tried using my phone and work computer.
