Is there a way to change the owner of a snap?
Yes: the operation is called a “transfer”. It can be requested here in the forum (store-requests category, please) and we’ll need the name or account id for the recipient’s account (which must be that of a developer who has signed up to snapcraft.io and accepted the developer terms of service), as well as the snap’s name or snap id.
We usually email both the current and the new owner to confirm the intent.
I added a request in the store-requests to transfer the ownership.
