Do failed passcode attempts prevent a child from sending screen time requests?

Do failed passcode attempts prevent a child from sending screen time requests? I told my daughter to send me a request for more time. She made the request but neither I nor my wife received the notification. She asked me to enter the passcode directly on her device and I told her again to send me a request. Again we did not receive it.

Once I finally entered the passcode on her device it notified me that this had been my seventh failed attempt. Could my daughter have been attempting to guess the passcode? Could her failed attempts prevented her from using the 'ask for more time' feature?
