Thumbnail Preview

It was amazing - one day the Ring app notified me of a new notification for the Doorbell Pro, where it told me that there was movement in front of my door, but also showed a thumbnail preview!This is on my iPhone, lock screen notification. Upon 3d-press, it opens up the notification with the options to snooze, but also the thumbnail! love it!2 days later, it goes away. I can't find anything in the app about the thumbnail preview, and the online chat support only got me to re-install the app, turn notifications off and back, just to say, "yes, text notifications are the default", and not answer anymore to let me know why it happened in the first place. Anyone figure out how to turn this feature back on? Or was it just a tease? April fools is not for another couple of months :\
