@Riley_S I seem to have the same problem.  Ever since the SD card filled the first time the camera will not display a recording.  Some days there are no recordings listed even though there are events that should trigger a recording. Other days there are recordings in the list, but when clicking on them there is just are round a round symbol that never stops and the day field always displays --:--:-- --.  I tried reformatting the SD card within the KASA app but that didn't fix the problem.  Is the the same problem that will be addressed by the firmware update you mentioned?

I just had the same issue today as well. I have a model KC411S, with hardware version1.0 and firmaare version 2.3.13.    I don't know what a MAC address so I don't know if I should post that here, but I can give you that if it is useful for anything.   I am using Sandick 256GB ultra plus for my card.  I've had a landlord sneaking into my office and I wanted to catch him.  I've been closing a certain door to know if he was coming in or not previously, and would occasionally find it open, and sometimes he even forgot to restart my alarm.  That's why I bought the camera.  I get lots of motion alerts because the cars on the streets trigger alerts as they flash on the hallway walls.  No big deal. I can always do a quick check and see if that door is still closed and I would know.  But, today I got an alert, and on the live feed, I saw the door was open, and therefore I went in and looked for the video feed and It wouldn't come up to replay.  Live video worked, but not recordings, so I couldn't view the entry I was wanting to see. 

So, I drove in to the office to try to see if something was wrong with the camera. It is still working live, but wouldn't pull up past videos.  I then took the card out and downloaded it to my PC.  I was unable to view the MP4 files on the card on anything I could try.  I even downloaded VLC media player as i saw on one post here, and it wouldn't work.   When copying, there were two files that wer unable to transfer.  They were both MP4 files and the error code was "0x80070570: the file or directory is corrupted and unreadable"  on the windows 11 transfer popup for the error.    I don't know if this helps at all. 

One more thing, I did format the card I believe it was earlier this week.....if not, then it was last week.  I noticed things were loading slower to review videos that recorded, and I looked at the memory available, and I noticed it was getting low, so I did a reformat to get a fresh start.  It was working fine after that from what I could tell.

One last thing.... I took the card out to download the videos to my computer and they wouldn't play on the computer either.  So, I put the card back into the camera, and

 new videos started to record properly.  I then took the card out again to try to view it on my computer just to see if there was anything different with the old videos.  I was able to view the newly recorded videos (after the card reinsertion), but I was still not able to view the previously recorded videos on my computer.  I put the card back in the camera, and I was able to view the new videos, but still not the old ones.  It looks like it recognizes that there are old videos to view, but can't download them.  

I hope this is some info that could be helpful in debugging.  I just hope I didn't lose the video of my intruder.  Lets just say that what was once a great landlord/tenant situation has gotten really as someone has given him some very poor advice.  He has broken a lot of laws, and I have proof, but these videos would be the final proof I need to pursue legal action with a slam dunk piece of evidence like actually seeing him, and probably someone else with him as witnesses have said in the past.   Thanks for the help.

I had a similar problem with a new EC70. See Chat ID 16809398. The 24/7 feature seemed to be recording by looking at the sd space and the progress bar on the 24/7 view section. However, I could not display any of the recording. I tried new sd cards, reformatting the sd card through the app, etc. Nothing worked. I did not reset the camera through the app or the hard reset button. I then deleted the activity zone I set originally. Then recording and viewing 24/7 video worked. Somewhere there appears to be a glitch between the 24/7 system and the activity zones.

Does anyone know if there has been a resolution to the issue of not being able to play back recordings?  I have two of the KC420ws hardware 1.0 and firmware 2.3.13.  Nothing seems to help. Formatting nor resetting makes any difference. 

Having similar issues here. I have two KC410S that work fairly well. It's my two KC420WS that frequently display "Your camera hasn't recorded anything at the current moment" when trying to playback. Just can't seem to get them to record everything regardless of motion. Reformatting the SD card seems to make it work again for a couple days, sometimes..

I keep hoping for new firmware for this model. Currently at 1.0 / 2.3.13 / 2.39.0 / 1044

Is there a way we can recover the corrupted files from the SD card?  I am in a similar "Murphy's Law" scenario and need to recover some footage from this morning and I cannot open any of the recorded files.

  @Riley_S If it helps, I can confirm that all of my cameras have 256GB cards and it does seem to occur more often when the card is nearing full capacity. I thought reformatting just got things going again but this makes sense if the behavior is related to available space.
