That was my first thought, too – an update or something reset the Terminal settings – so I did what you describe (logged in with credentials, checked the settings, logged back into API mode). None of them were set to show the reciept/ask for signature, but I toggled them anyway just in case.
So far, that hasn’t fixed it. I suppose I could try it again and see what happens.
@Bryan-Square Any ideas, since you were able to help with this last time?
