Now that I've tried this process with another user who uses the same computer, he is running into issues with the "Move" process as well.

He was able to get data to move using the "Copy" button, but when he tried "Move" it did the same thing and froze without any progress. I can see that the Pro free trial shows up for him, but it is not fixing the problem.

I am hesitant to purchase the pro license when it is not fixing our problems.

I waited an additional hour after my last response and still no progress! I will look into getting the Pro version, but it's unfortunate this is not working in the free version.

Edited to note that this has been the case every time, and we've waited things out for way longer than we needed to with no progress, and we did not see any changes in the S3 bucket while waiting for it.

It seems like it's mostly happening when there are multiple nested folders with files inside them, rather than being dependent on size. For example, one folder I'm using for testing is 260 MB, with 24 folders and 479 files. It still froze with that small of a folder. My upload speeds at the moment are ~2 Mbps, and I've waited over a half an hour with no change in the completion. With very small folders and files the completion shows up fine as it progresses. Based on your response, I tried the free trial and the same "move" task worked fine.
