Why isn't she seeing my texts? 🥲😢

2 days ago, I posted that i finally got my crush Akankshya's phone number in a really clever way. I was learning about Google Forms in classes and made a car related survey on Google Form and said her to fill it as its an important assignment. So I asked her number so I can send the form to her throught Whatsapp. She gave me her number and said me to send it on her whatsapp and she will fill the form but its been 2 days and she didnt even see my text on whatsapp yet. I again sent her a follow up text today writing this "hey can you please fill the form as today is the last date to submit the assignment" but still she didnt see the message 🥲😢. She probably turned off her online status on whatsapp so can't even see when she is online. I am still keeping some hopes because often briefly talk in person. She is within 21-23 age range and I am 23 too. She is very pretty almost model like and I find her really cute and feel butterflies.
