Maybe we did something wrong but we created u.kraine.eth with the namewrapper, however it does not show as registered on any marketplaces.
It is searchable and editable on v2 and v3 versions of the ENS app, but does not show in our collection nor does it appear in a search on opensea or other marketplaces (ENS.VISION shows as invalid but that looks to be just a coding issue on their side)
