Access Denied to Bucket after Successfully Savind Settings

I recently installed WP Offload Media Lite, just to try it out. I have correctly configured the plugin and got it pointing to a valid bucket on AWS with an IAM user linked to the “AmazonS3FullAccess” policy. When I initialize all the settings, everything saves fine and it looks like I’m good to go. However, when I return to the settings page, I am greeted with the following error message:

Access Denied to Bucket — Looks like we don’t have write access to this bucket. It’s likely that the user you’ve provided credentials for hasn’t been granted the correct permissions. Please see our Quick Start Guide for instructions on setting up permissions correctly.

Clearly, I have done nothing to my AWS setup! This happens repeatedly. I have tried changing the keys for my user and am then subsequently able to save changes again, but if I EVER go back to the settings page, I see the same error message and cannot save any changes I make to the settings.

This is clearly a bug and needs to be fixed.
