Floodlight Cam event video stuck at some point so we cannot see anything

Recently we noticed that very often times the recorded event video was stuck at some point, which means it missed very important event monitoring. For example, someone entered our backyard on 4/29/2020 7:22AM, camera started to record 2 seconds before the event, however, since 00:04, the video was stuck until 00:50 seconds, it was just a still frame. We lost all event monitoring during this time period.This also happended when yesterday a mailman came to front door to drop off a package, the video was stuck we could not see what happened.I tried to download the video and it was the same, so nothing relates to network when watching the video.This is a very serious issue since camera did not capture important video.
