"Shared with You" photos not showing up
"Shared with You" photos are not showing up in Photos. I have tried every solution I could find online, toggled every option, restarted, plugged in to power, etc. and nothing has worked. I'm having the problem on a new iPhone 15 and an older iPhone 11, both running the latest software updates. Funny enough, it works on an older iPhone 8 running iOS 16.7.11. I am at a loss. It is so much easier to have shared photos show up in "Shared with You" than saving them individually from Messages.
