samsung – My Galaxy A71 photos aren’t being picked up in Google Photos

I’ve got a relatively new Galaxy A71. With all my previous Android phones, my camera photos automatically got picked up in Google Photos. This phone, for some reason, doesn’t work that way; if I want my photos to upload to Google, I have to select and share them manually. Inside Google Photos itself, in the section to select “Device folders”, it tells me “Your camera folder is automatically backed up.” But, fact: it’s not.

How do I fix this?
