cache-control headers are not being set when uploading to s3 using filepicker.io. this is causing the wrong content to be served when the files are requested.
Unfortunately, there is no way to force filepicker.io to send cache-control headers to Amazon S3. However, you can try using a third-party service like CloudFlare to add the necessary headers.
At the moment, filepicker.io does not send cache-control headers to Amazon S3. However, you can contact their support team and request that they add this feature.
