Anyone to make uploads to ACD reliable?

Right now the failure rate on rclone copy to ACD is extremely high. It took me six attempts to rclone copy one file yesterday and today it seems just as bad.

Is there anyway to prevent the 100% done, wait 2 hours, restart, wait 2 hours, restart issue with ACD?

It’s becoming so bad, it is virtually unusable.

There is a resume API for ACD which Amazon aren’t publishing. It is in use by their desktop client. This would help a lot. So if you know anyone at Amazon ask them to publish the API!
