Upload Error when trying to send large files with Adobe Send

I am a paid subscriber of Adobe Send and should be able to send up to 2GB of files. I am not able to send even 1GB. I have compressed all files into a .zip folder.

I then tried splitting the files into 2 separate .zip folders at about 500MB each, and still got the upload error again after waiting for the entire file to upload. A lot of wasted time now.

It's not reasonable for me to send all of the files piecemeal to my client.

What is going on?

Thank You!
