Hi,
Please confirm the following information for the reported issue.

1. What's the model number, capacity, and format of the SD card inserted into the camera?

2. On the Tapo app > Camera's Device Settings > Storage & Recording page:
1) Go to the Local Storage page and send me a picture of it.
2) Go to the Recording Schedule page and send me a picture of it.

3. On the Tapo app > Camera's Live View > Playback & Download > Playback page, if you select the date before Sep 11 and then tap the SD card icon, can you see any video recordings?
Can you send me the pictures showing the reported issue?

Best Regards

Hi,
Usually, the snapshot will appear when the detection feature is enabled and works. 
In your case, please go to the camera's Device Settings > Detection page to check what detection types you have enabled.
Then ensure the Notification feature is enabled on the Device Settings page and go to the Tapo app > Home tab > Bell icon > camera page to check if you will receive notifications when the camera detects events.

If the detection feature is not working, you can refer to the instructions below to troubleshoot.
What to do if the Detection feature is not working on the TP-Link Camera?

Hi,
In this situation, if you can watch the video recordings on Sep 11, 2024, and prior to Sep 11, but all snapshots on the Tapo app > Camera's Live View > Playback & Download >Playback page disappear, please refer to the following steps to record a video showing the reported issue for further analysis.

1. On the Tapo app > Home tab > Bell icon > camera notification page, please find the one or two received Person-detected and Motion-detected notifications before Sep 11, 2024, 7:00 PM, and record the received date and time.

2. Go to the Camera's Live View > Playback & Download >Playback page, select the date to Sep 11, 2024, click on the SD card icon, slide on the timeline, and find the video recordings according to the time recorded on Setp 1.
Then you can use another phone to record or turn on your phone's Screen Recorder feature to record that there are motion/person detected and video recorded but no snapshot displayed.
You can upload the video to your cloud server(such as Google Drive), generate a link to download the video and send me the link via a private message.

What's the model number and OS version of your phone? What's your Tapo app version? 

Best Regards

Hi, 
When the problem happens, whether the snapshots under the timeline disappear? 

Please refer to the instructions below to collect the camera log, and let me know when you have the log file. I'll escalate your case to the tech team for further analysis.

Btw, what's the model number, capacity, and format of your SD card?
