I have a Pixel 6 and the Dropbox app won't upload photos taken on my phone. Things I've tried:
1) Toggling photo backup off and on (several times)
2) Purging the app cache, forcing a re-login
3) Logged out, logged back in
4) Uninstalled, re-installed Dropbox from scratch via Google Play Store
If I go into the Dropbox Camera Uploads > hit the plus sign > and take a photo, that photo immediately uploads. So that functionality seems to be intact. When I take a photo with the Android 6 camera app, that photo doesn't show up anywhere in Dropbox - but it shows up in the Photos app - so it seems as though the Dropbox app can't "see" the photos I'm taking on my phone.
My wife's phone is logged into my account as well for photo uploads, and photos aren't being uploaded from her phone either.
Any known fixes for this? It makes Dropbox 100% useless for me since my primary use case for Dropbox is photo transfers. Everything seemed to be working well until a few weeks ago, but I didn't purposefully change anything.
