"I paid but it says Trial"
PhoneLeash licenses are tied to the forwarding destination.
At the time of purchase if your forwarding destination was bob@myemail.com but later you decided to forward instead to alice@myemail.com your app will revert to Trial mode.
After 30-days your trial will end and PhoneLeash will pause. If you have used this new address in Trial mode before, it could pause sooner.
If you want to change your destination without losing the license, email support@phone-leash.com (please be mindful and not ask to change more than twice a year).
