I have changed the storage from google drive to Amazon S3 bucket. All are fine with the new items created (including display images and open file). I have moved the existing images and uploaded files from Google drive to S3 bucket also, and still keep the data file spreadsheet in its current place on Google drive. Unfortunately, the images and uploaded files can not be viewed/displayed after moved to S3 bucket. I doubt why it works fine with the new creation items but cannot work with the existing items (although I have moved images/files to the correct path on S3 bucket). Does anyone get the same situation? please share your experience.
