Google photos shows no photos in All tab I have been noticing that the Google+ Photos application does not show any images in the All tab (the Highlights tab works fine). I have a lot of photos but they show up fine in the stock Gallery app. Any ideas? 

The device is the Nexus 5 which does not have an SD card.

I tried clearing the cache (suggested here) but the Photos app is not listed in Settings > Apps.
Google+ Photos doesn't exist separately - it lies within Google+ main application. I mean Google+ Photos app comes along with Google+. So you need to clear the data of Google+ in app manager. Also you can uninstall the updates of Google+ and update again if clearing the data doesn't work.
