I am on the free plan. I am the only workspace member and have 7 guests who are all single board guests, with 2 being an admin. I am under the collaborator limit (8/10), and I have no pending join requests. Yet, I am unable to add guests, and there is no 'Share' button anymore for some reason. I cannot make any guests an admin, only add them to the workspace as an admin.

When I created a copy of the board, I was able to invite guests in the copy of the board, with the share button being there, as if everything was fine.
I don't want to use the copied version of the board, and I don't want to add more workspace members, just guests. Do you know what I can do?
