Anonymous users can't submit screenshots

Not able to reproduce , I can see the screenshot attachment in submitted feedbacks.
Can you specify if there are any other steps , I have followed as in description
Steps Followed :
1. Enable website feedback
2. Enable screenshot option in website feedback settinngs
3. Provide permission to the anonymous user to submit feedback
4. As anonymous user submit the feedback
5. Check the submitted feedback

- I can see the screenshot which was submitted in feedback

I can reproduce the problem with your steps.
I suppose we have a difference in our environments.

Do you have private files enabled? It seems I don't have this problem if the screenshot is uploaded to the public file system.
You could try adding this at the beginning of steps to reproduce:
1. Add $settings['file_private_path'] = '/foo/'; in settings.php.
2. Rebuild cache (drush cr).
3. Browse to /config/media/file-system and set the default scheme to private.
4. Rebuild cache (drush cr).

Hi there, testing this using D11.2.2 site with website-feedback version 1.1.0.

I was able to reproduce this error when submitting as an anon user and with the setting "Default download method = Private local files served by Drupal". Result is screenshot not showing.

I was also able to reproduce the error when submitting directly from the admin/content/website-feedback page (also as anon user + private setting). Same result - screenshot not showing.

If I ran the same two tests with the setting "Default download method = Public local files served by the webserver". Result was that - Screenshots did show.

Then I retested using issue branch 3538394-. In all test combinations (Private or Public, Sidebar or Add page) the screenshots show ok.
