If you noticed that the data on your Control Panel is not updating, there could be at least two reasons:
Check the Internet connection: all target device data is uploaded to your Control Panel over the Internet. If the Internet is weak or disabled, the received data will not be uploaded to your account. Consequently, you will see no updates there.
Check is the app is still on your target device: to receive insights into your target device activities, the CatWatchful app should run on the device you are spying on. If it was deleted, you would not be able to see any updates on your Control Panel.
