Except they don’t read it, shoot themselves in the foot and then come on here and ask how to fix it.
Search for topics on v2 gateway deletions - only when pushed does the OP admit to having clicked on the dire warning in the console. And even then it’s “not their fault” and expect someone here to dip in to the database to fix the problem.
I’ll look again at the flow as I’m not sure how the user or you or the database distinguishes between the owner of an object and the other collaborators. But if there is only one collaborator entry for a gateway that must be the owner and perhaps not allowing any edit of rights would be appropriate.
