@tm_karl​ My email(not Apple account mail) links with my phone. I tried to Sign in with Apple. It turns out “there is no account with this mail”.

Hi @leonachen6,

​I've checked your account here and there's no active license. Are you able to contact Apple support for this transaction? 

@tm_joyce​ I did the payment.

When I tried to buy again, the system popped up this.

Who got the payment?

Hi @leonachen6​, 

Because this was purchased within the app, the charge came from the Apple Store. To ensure your mobile security reflects the subscription purchased from the Apple Store, you need to click on 'Restore Purchase.'

To restore your purchase, please follow the instructions below:

1. Launch the Mobile Security app on your device.
2. Tap on 'Settings.'
3. Tap 'Buy/Activate'
4. Select 'Restore Purchase,' then tap 'Check Now.'

Please let us know how it goes. Thank you!
