I'm developing locally and adding images to my Amazon S3 bucket. I have the same connection to the bucket on my remote environment. On my local environment, I can see the images I've uploaded, but on my remote environment none of the images that I uploaded locally are showing when I browse assets.
On my remote environment, if I attempt to re-upload the image, I get a message: A file with the name “mylogo.svg” already exists. So I know that the assets field is correctly connected to the bucket in the remote environment.
