Airdrop is only working one way

I have an iPhone 12 and my daughter has an iPhone SX. She can airdrop photos to me but I can’t airdrop to her. Her phone doesn’t even show up. I have tried looking at the settings and we both have everyone. I turned mine off and on again. I turned the WiFi and blue tooth off and on and have rebooted the phone and no luck. Can you help?
