The option for mobile check-in should display on the event too. I posted this in the Feedback, but thought I'd share it here too.
It took me a while to find the new Mobile Check-In tab in the new app. I kept going to the event expecting to see the option there. It wasn't explained very well as to how you check-in on mobile. I never got a pop-up notification, so I kept looking in the event. Also, was never able to scan my code and when i tried to input the 4 digit code, it never pulled up my check in.. There isn't enough instruction on the how to check-in with the code part. Love the new feature, just needs more explanation. A video for the member on how to use it would be great!
