Is Ring working on a way to look up a specific timestamp that has not been registered as a recorded event on a Ring Doorbell? I have had numerous instances where I have supposedly had a package delivered I have no recording of the delivery and there is no way to cross-reference the purported delivery time with my Ring Video Doorbell. I fell like this would be a feature most Ring customers would want to help in the instances of missed deliveries, thefts, and other crimes.
If there was no recording, then there is nothing to timestamp or look at. The Ring cameras only record on motion, so if there was no motion detected there is nothing to put on a time line. If you are missing activity, you might need to play with your sensitivity and/or zone settings. I had to timker with mine for a few days to get my cameras tuned.
