Hello   @HenryGr 

If Playback does not load,try rebooting camera first.

Confirm kasa APP & device firmware are both up to date. 

Try a different phone and see if this is related certain phone

If camera 24/7 was working fine before , try factory resetting camera and set it up on Kasa app again and see you could access 24/7 recording. 

Check modem & firewall settings and see if any request from camera MAC has been blocked

May I know the ISP and model of router, e.g. ISP Spectrum modem - router <wireless>camera, APP version, model of phone and its Andriod/ IOS version

Can I have a photo of the error page/ loading page? Thanks!

  @JodaJacksoncatr Hello, thank you for asking, kasa camera with SD card feature uses loop recording automatically and camera will overwrite the oldest footage when SD card is full. It is recommended to usea  high enduration SD card or use the SD cards which is advertised to be suitable for security cameras.
