Hi,
Thank you for your reply.
One drive add-on is right now in reconstructing state and it will be available soon.
Also, redirecting will not occur with other cloud options like google drive and Amazon S3.
However, with the WPDM Pro, you will be able to download files without redirection as we are using a custom Dropbox API
to handle downloads properly.
I hope that helps. Let us know if you have any further queries.
Regards
