Google has increased the size of attachment from 20 MB to 25 MB !
Google suggests “With Gmail, you can send and receive messages up to 25 megabytes (MB) in size. Please note that you may not be able to send larger attachments to contacts who use other email services with smaller attachment limits. If your attachment bounces, you should invite them to Gmail”
Also make sure that you have enabled “Advanced Attachment Features” under “Settings” –> “General” –> “Attachments” –> Enable “Advanced attachment features”.
20 MB + attachment works smoothly in Chrome, I have not verified the same in Mozilla or IE.
