Unfortunately that's just temporary. This morning 08:03:50 it flicked back to night mode. At 09:15:00 it swapped back to day mode. At 09:36:00 it swapped back to night mode again. Tapo must address...

@AlexTheGreat89 Thank you for your advice. I did the same, Tapo replied pretty efficiently. All I need to do is to turn the Video Mode back to Auto. Then go to Settings - Reboot Camera. Now it works...

@Mattyboi001 Same like everyone else, after the firmware updated, the video mode stayed at night mode.
