I recently joined Facebook, downloaded the app on my iPhone 10, and have the latest update of iOS.
Since joining Facebook last week, I have not opened the closed Facebook app on my phone, but have seen that I have new notifications pending on it per the Facebook icon. I have taken several photos on my phone that are on my camera roll that I don’t wish to post or share.
When I signed up for Facebook I regrettably agreed to allow Facebook to access all photos.
Since I haven’t opened the Facebook app since I have taken new photos on my phone, does Facebook have/see my current camera roll.
Normally Facebook should ask you for permission to access your photos each time you install the application on your phone. For that reason, I would personally recommend you to delete the app from your phone, download it again and carefully revise the permissions your iPhone asks you to give during the installation process.
