Our company is using JIRA in the cloud. A user emailed comments to a ticket using the correct email address and also putting the issue number in the subject line. I can see that the comment was logged in the ticket, but there is no text, only an expand/collapse button, which reveals nothing. I have verified that that user has the correct permissions to Browse Projects. I am an administrator of the project and I cannot see the comments either. I also tried adding comments to the ticket via email as well and see that my action was logged but not the text of my email.
