You can delete button native jira?

[Bruno Capanema]

When you select permission on where the user can assign issue, the flowappears on a button and users are responsible for using it the wrong way, how do I delete this button, without removing the atribur permission issue?

[Nic Brough -Adaptavist-]

If you were on Jira standalone, it's possible to hack the link off the screen. That won't stop someone who knows the url from using it, but makes it hard. I don't think you have that level of access in OnDemand.

Sounds like you don't want your users to easily assign issues to others. I am afraid the only way to prevent this (and thus, to remove the Assign button) is to remove their Assign Issue permission.
