since the update to version 5, when changing the ticket to “wait for …” an additional query “wait until” appears.
How can I hide this query or at least leave it “empty” in order to change the ticket?
Do you mean the input field for the wait until date? That has always been there and is the whole point of the states “Warten auf Erinnerung (pending reminder)” and “Warten auf Schließen (pending close)”. If you want to have another state that doesn’t ask you for a date you can create new ones that don’t require a date input.
