Hello,
Your Changelog page for Remote Storage for RS Form Pro throws an error (blank page): https://nswd.co/extensions/help-desk/categories/remote-storage-for-rsform/remote-storage-for-rsform-change-log
Also, any idea when you will be adding support fore Google Drive? I purchased the plugin partly on the basis that the plugin's product pages said Google Drive support would be added in June 2017. I waited but it hasn't come so I had to purchase an S3 account. I would prefer to use Google Drive because it's easier for the client to use (and it's also free unlike S3).
Thanks,
Joseph
