Just wanted to mention United Club members need to present the physical United Club card at the MLL entry. They don't accept the "digital" membership card built into the United app. I was initially denied entry to the YYZ transborder MLL last week because I didn't have the physical card. As the dragon pointed out, tapping on the digital UC card reveals the message "This digital card is valid only at United Club locations". After a brief scolding, she did allow me in after pushing some buttons on the computer, something she said wouldn't normally be done if they had a line up of people to process.
