As a Roblox group holder, it is currently impossible to transfer ownership to a user who’s username gets filtered in the search tab.
I ran into this problem just minutes ago when my friend had asked me to make a group and transfer it to him. If Roblox were to address this issue, it would make it a lot easier for one to move the group ownership without having to worry about the filter.
Alternatively to the suggested idea (since misclicks also happen), there could be a scrolling frame with the existing members since you already need to be a part of it to have the group transferred to you.
I encountered this issue yesterday and I got around this by using the endpoint available here. Be sure you are logged in. Click the model value on the right and change the userId value to who you are passing the group to.
Thanks for the report! We will put in a fix for this to directly look up by username if the term is moderated by the search endpoint. In the meantime, I recommend calling the endpoint directly like @Qxest suggested above
You’re no longer able to claim ownership of a group if the Group Owner leaves. When the group owner leaves a group, it’s just owned by no one. In fact it literally says: “Owned By: No one,” and group members no longer have the option to claim ownership of the group.
I’m gonna need a little more information than that. Is the search query moderated? Is the user not showing up in search? What is the group id and what is the username?
