We have tested on the latest version of WhatsApp '2.21.19.21' with the latest version of FlexiSPY for Android (Advanced) and cannot recreate your issue.
That said you were not using the latest version of FlexiSPY (5.3.2) which contains improvements to WhatsApp capturing and so we have remotely upgraded FlexiSPY on your device to the latest version. We also see that you are using an older version of WhatsApp '2.21.14.24'. Please send and receive a WhatsApp message on the Target device and if outgoing messages are still not captured then please upgrade to the latest version of WhatsApp.
