Hi @Nikki404
Did the old listing managed by the property management have any listing issues or negative reviews?
Suggest to Contact Airbnb Support (Again, But Differently) Ask specifically for the issue to be escalated to a Trust and Safety team member, since this is about a platform policy (duplicate listings).
Prepare a concise explanation of what happened: that the former property manager mistakenly left the listing active, causing Airbnb to flag yours as a duplicate.
Include any written communication with the former manager (email or message screenshots) where they confirm their error and that the original listing has now been removed.
Keep the tone professional, firm, and focused on resolution.
Hope this helps, wishing you the best of luck! Keep us posted on how it goes.
