I have created an Alteryx app by using 'Connect in-DB'. But when I share the app to other people, they got an error message that they cannot connect to the server (LockInInput (2): Error finding connection 'LONDON11'). My teammate said the app users need to change the connection on their side or log in to the server, and then to use the app. I don't have any problem to share the app when the input is a file. Is there any setup I should do?
