We have added a new option to allow files to be attached to a private message. The files will be deleted in 30 days after uploading the file and the file size is 10MBs max.
Below is the file types allowed. If you would like a certain file type (or size) to be added (that isn’t available) to the attachment options, send us a support message. The support message section can be found on the bottom bar (desktop) or in the menu bar at the top (mobile).
