How do I attach files to comments?
When adding a comment to a card you will see a paper clip icon. Click on it to attach files from your computer or Google Drive.
You can attach any type of file. They will be attached to the comments section only, and won’t be added to the attachments section.
It will help you to keep the attachments section tidy and add only the main assets there. While all drafts and files to be discussed may be attached to comments. Also, you may leave a comment and mention your colleague if you want them to check any document quickly.
