Waste of an update. Insists on a mandatory app check-in, but not viable. Check-in via email, lead me back to the app, only for it to tell me I've checked-in and to proceed to the counter for my boarding pass? What happened to paperless, reducing contact, etc? Before something is made mandatory, please, make sure everything is in order. Now will have to waste at least an extra 1.5hrs -2hrs of my precious time just so I can sort this out. Sort this out please!
