Hi @Soenneker 
Sorry for the belated response. I’ve just enabled the setting and given it a run-through on my test site to check and I’m also seeing similar behaviour, but only if I don’t refresh the page before trying to perform the permanent delete.
My step-by-step:
- Soft delete an existing post
- Open post wrench and click ‘Permanently delete’
- ‘Are you sure you permanently want to delete this post? You will not be able to recover it.’ confirm modal appears
- Click on ‘Yes’
- Modal closes, but no response. Post remains soft-deleted
However, if I add a page refresh it works as intended:
- Soft delete an existing post
- Refresh page
- Reveal soft-deleted post using ‘View hidden reply’
- Open post wrench and click ‘Permanently delete’
- ‘Are you sure you permanently want to delete this post? You will not be able to recover it.’ confirm modal appears
- Click on ‘Yes’
- And the post is permanently deleted (as long as I’ve waited 5 minutes, or used a second test user with admin privileges)
Does this sound familiar, or could I try something else to replicate what you’re seeing?
