In the Permissions setting, you can configure the “View issues” attribute.
Is there any way that the end user can see her issues only? (creator/watcher). For our case, we want the end users to submit comments/issues for an application. These users should see their requests only to check the progress, etc.
Not at the moment, I’m sorry. In Taiga, you can only configure permissions for all external users, which means a user would see not only their own open issue but also those of other external users. The user can search for their issue using keywords, but of course, it’s not an automated process.
We’ll keep this in mind for future improvements
