Tapo HUB H200 fails to show playback if the camera (Tapo C420) is battery dead / disconnected

I have TapoC420S1

Which has 2 devices 

1.Camera (C420)
2.Hub (H200)

I bought it as it has an isolated recording and not an onboard memory card feature.
Thought was in case the camera is stolen, the recording will still be there on the HUB and I will be able to see it.

But recently, my camera got battery dead. And I wanted to check the old recordings that were stored on HUB
But to my surprise, App fails to show any recording on HUB playback, not even the ones recorded on its memory card.

I request Tapo Team to please fix this issue, because lets say if the camera is destoryed / stolen by a thief then having the HUB was totally useless
Please Tapo team, fix the issue and allow the user to see the old recorded saved videos which are stored on the Tapo HUB's Memory card from the APP.
