Was there a change with mobile key for the most recent android app update? I could have sworn I successfully used mobile key at a property on Sept 21. Now I've just had 2 consecutive single night stays at different properties and did mobile check-in on the app for both. For each property, I received push notifications when my room was ready and available, then followed by the push notification that told me my room #. However, the mobile key icon never appeared on my app for either property.
