 ## Frequently Asked Questions
 
-- `downloadData` is cached; if you have recently modified a file you may not get the latest version right away. You can pass in `cacheControl: 'no-cache'` to get the latest version.
-- `downloadData` only returns the latest cached version of the file; there is [not yet an API to view prior versions](https://github.com/aws-amplify/amplify-js/issues/2131).
 - [Image compression](https://github.com/aws-amplify/amplify-js/issues/6081) or CloudFront CDN caching for your S3 buckets is not yet possible.
-- There is no API for [Cognito Group-based access to files](https://github.com/aws-amplify/amplify-js/issues/3388).
-- There is currently [no API for getting the `identityId` of other users](https://github.com/aws-amplify/amplify-js/issues/5177); you have to retrieve this from elsewhere before calling `Storage.get`.
+- `downloadData` does not provide a cache control option and it replies on runtime HTTP caching behavior. If you need to bypass the cache, you can use the `getUrl` API to create a presigned URL for downloading the file.
+- `downloadData` does not support S3 object versioning, it always downloads the latest version.
