How to install Norton 360 for iOS on iPhone which has another Norton contract expired

I had old Norton contract on my iPhone and I didn’t continue the contract and it expired. The contract was for only 1 iPhone. On the other hand I bought another Norton 360 for 3 devices and tried to install this new Norton on my iPhone, but I can’t. When I try, iPhone shows the message, your contract canceled. But this new Contract is working on my iMAC. Please guide me how to install to my iPhone.
thank you and regards,

On an iPhone, the only way to clear all app data is to uninstall the 360 app. Then when you install again, look for a Sign in or I already have a subscription link and tap on that to log into your Norton Account to activate the new subscription on your device.
