Question [Q] Google Photos App - Where are my Automatic Backup photos?

Hello,

as my Nexus5 was stolen I switched back to my Galaxy Nexus Maguro installing PA 4.0 in Beta4 with PA Gapps Modular.

I see there's no more Gallery App but the new Google Photos App. All my previous photos from my stolen phone are in the Automatic Backup porting of my Google+ account, I enabled Sync on and Automatic Backup on my Galaxy Nexus but cant find the Automatic Backup photos from within the Photos App?

Anything I am missing or any setting I have to enable???
