Hi , I submitted an add-on from my account and I deleted the same from my account. On submitting the add-on again , it shows an error as “ **Duplicate UUID found** ”. Can anyone help me with this? @jorgev. Please resolve it as soon as possible.

Try changing your version number. Just a shot.

Your deletion is what caused the error. Don’t delete addons, there is never any reason to do so. Now you must wait until an admin has time to investigate and free the UUID for you.

It might be easier to just create another UUID, is that a possibility @muthukumarcse1?

Please email amo-admins at mozilla dot org with the add-on ID.

I want the same UUID for my add-on and also changing the version number will wont work because add-on are uniquely identified by their UUID. Version Number is modified only when an update has to be given to the already existing add-on @noitidart

What was the reason for deleting your add-on?
