Deactivated Listings
Listings are deactivated if the listing creator does not respond to a trade request.
By not responding, it shows that you are not available to perform trades.
Deactivating listings prevents others attempting to trade with users that are not available.
This ensures a good user experience for all involved.
Steps to reactivate listing
From the home screen, tap your username.
Your account will be shown to be in Sleep Mode.
If you tap Active, your listing will become active again.
