I was in a Freinds+ instance and wanted to invite a friend. For some reason, from the QM the Send Invite button was grayed out and not clickable. Then I went to the MM and the Send Invite button was still grayed out but also clickable. I clicked it and the modal for sending an invite popped up and I sent the invite. The friend reported that the invite went through successfully. Why was it grayed out in the first place, and if it was disabled for some reason, why did it still work?
